Introduction
Azurite is an open source Azure Storage API compatible server (emulator). Based on Node.js, Azurite provides cross platform experiences for customers wanting to try Azure Storage easily in a local environment. Azurite simulates most of the commands supported by Azure Storage with minimal dependencies.
Azurite V2 is manually created with pure JavaScript, popular and active as an open source project. However, Azure Storage APIs are growing and keeping updating, manually keeping Azurite up to date is not efficient and prone to bugs. JavaScript also lacks strong type validation which prevents easy collaboration.
Compared to V2, Azurite V3 implements a new architecture leveraging code generated by a TypeScript Server Code Generator we created. The generator uses the same swagger (modified) used by the new Azure Storage SDKs. This reduces manual effort and facilitates better code alignment with storage APIs.
3.0.0-preview is the first release version using Azurite's new architecture.

Getting Started
Try with any of following ways to start an Azurite V3 instance.
GitHub
After cloning source code, execute following commands to install and start Azurite V3.
npm ci
npm run build
npm install -g
azurite
NPM
In order to run Azurite V3 you need Node.js >= 8.0 installed on your system. Azurite works cross-platform on Windows, Linux, and OS X.
After installation you can install Azurite simply with npm which is the Node.js package management tool included with every Node.js installation.
npm install -g azurite
Simply start it with the following command:
azurite -s -l c:\azurite -d c:\azurite\debug.log
or,
azurite --silent --location c:\azurite --debug c:\azurite\debug.log
This tells Azurite to store all data in a particular directory c:\azurite
. If the -l
option is omitted it will use the current working directory. You can also selectively start different storage services.
For example, to start blob service only:
$ azurite-blob -l path/to/azurite/workspace
Start queue service only:
$ azurite-queue -l path/to/azurite/workspace
Start table service only:
$ azurite-table -l path/to/azurite/workspace
Visual Studio Code Extension
Azurite V3 can be installed from Visual Studio Code extension market.
You can quickly start or close Azurite by clicking Azurite status bar item or following commands.

Run Azurite V3 docker image with customized persisted data location
docker run -p 10000:10000 -p 10001:10001 -v c:/azurite:/data mcr.microsoft.com/azure-storage/azurite
-v c:/azurite:/data
will use and map host path c:/azurite
as Azurite's workspace location.
Customize all Azurite V3 supported parameters for docker image
docker run -p 7777:7777 -p 8888:8888 -p 9999:9999 -v c:/azurite:/workspace mcr.microsoft.com/azure-storage/azurite azurite -l /workspace -d /workspace/debug.log --blobPort 7777 --blobHost 0.0.0.0 --queuePort 8888 --queueHost 0.0.0.0 --tablePort 9999 --tableHost 0.0.0.0 --loose --skipApiVersionCheck
Above command will try to start Azurite image with configurations:
-l //workspace
defines folder /workspace
as Azurite's location path inside docker instance, while /workspace
is mapped to c:/azurite
in host environment by -v c:/azurite:/workspace
-d //workspace/debug.log
enables debug log into /workspace/debug.log
inside docker instance. debug.log
will also mapped to c:/azurite/debug.log
in host machine because of docker volume mapping.
--blobPort 7777
makes Azurite blob service listen to port 7777, while -p 7777:7777
redirects requests from host machine's port 7777 to docker instance.
--blobHost 0.0.0.0
defines blob service listening endpoint to accept requests from host machine.
--queuePort 8888
makes Azurite queue service listen to port 8888, while -p 8888:8888
redirects requests from host machine's port 8888 to docker instance.
--queueHost 0.0.0.0
defines queue service listening endpoint to accept requests from host machine.
--tablePort 9999
makes Azurite table service listen to port 9999, while -p 9999:9999
redirects requests from host machine's port 9999 to docker instance.
--tableHost 0.0.0.0
defines table service listening endpoint to accept requests from host machine.
--loose
enables loose mode which ignore unsupported headers and parameters.
--skipApiVersionCheck
skip the request API version check.
If you use customized azurite paramters for docker image, --blobHost 0.0.0.0
, --queueHost 0.0.0.0
are required parameters.
In above sample, you need to use double first forward slash for location and debug path parameters to avoid a known issue for Git on Windows.
Will support more release channels for Azurite V3 in the future.
NuGet
Releasing Azurite V3 to NuGet is under investigation.
Visual Studio
Integrate Azurite with Visual Studio is under investigation.
Supported Command Line Options

Note: The port in use is displayed on Azurite startup.
Workspace Path Configuration
Optional. Azurite V3 needs to persist metadata and binary data to local disk during execution.
You can provide a customized path as the workspace location, or by default, Current process working directory will be used.
-l c:\azurite
--location c:\azurite
Access Log Configuration
Optional. By default Azurite will display access log in console. Disable it by:
-s
--silent
Debug Log Configuration
Optional. Debug log includes detailed information on every request and exception stack traces.
Enable it by providing a valid local file path for the debug log destination.
-d path/debug.log
--debug path/debug.log
Loose Mode Configuration
Optional. By default Azurite will apply strict mode. Strict mode will block unsupported request headers or parameters. Disable it by enabling loose mode:
-L
--loose
Certificate Configuration (HTTPS)
Optional. By default Azurite will listen on HTTP protocol. Provide a PEM or PFX certificate file path to enable HTTPS mode:
--cert path/server.pem
When --cert
is provided for a PEM file, must provide coresponding --key
.
--key path/key.pem
When --cert
is provided for a PFX file, must provide coresponding --pwd
--pwd pfxpassword
OAuth Configuration
Optional. By default, Azurite doesn't support OAuth and bearer token. Enable OAuth authentication for Azurite by:
--oauth basic
Note. OAuth requires HTTPS endpoint. Make sure HTTPS is enabled by providing --cert
parameter along with --oauth
parameter.
Currently, Azurite supports following OAuth authentication levels:
Basic
In basic level, --oauth basic
, Azurite will do basic authentication, like validating incoming bearer token, checking issuer, audience, expiry. But Azurite will NOT check token signature and permission.
Skip API Version Check
Optional. By default Azurite will check the request API version is valid API version. Skip the API version check by:
--skipApiVersionCheck
Command Line Options Differences between Azurite V2
Azurite V3 supports SharedKey, Account Shared Access Signature (SAS), Service SAS, OAuth, and Public Container Access authentications, you can use any Azure Storage SDKs or tools like Storage Explorer to connect Azurite V3 with any authentication strategy.
An option to bypass authentication is NOT provided in Azurite V3.
Supported Environment Variable Options
When starting Azurite from npm command line azurite
or docker image, following environment variables are supported for advanced customization.
Customized Storage Accounts & Keys
Azurite V3 allows customizing storage account names and keys by providing environment variable AZURITE_ACCOUNTS
with format account1:key1[:key2];account2:key1[:key2];...
.
For example, customize one storage account which has only one key:
set AZURITE_ACCOUNTS="account1:key1"
Or customize multi storage accounts and each has 2 keys:
set AZURITE_ACCOUNTS="account1:key1:key2;account2:key1:key2"
Azurite will refresh customized account name and key from environment variable every minute by default. With this feature, we can dynamically rotate account key, or add new storage accounts on the air without restarting Azurite instance.
Note. Default storage account devstoreaccount1
will be disabled when providing customized storage accounts.
Note. Should update connection string accordingly if using customized account name and key.
Note. Use export
keyword to set environment variable in Linux like environment, set
in Windows.
Customized Metadata Storage by External Database (Preview)
By default, Azurite leverages loki as metadata database.
However, as an in-memory database, loki limits Azurite's scalability and data persistency.
Set environment variable AZURITE_DB=dialect://[username][:password][@]host:port/database
to make Azurite blob service switch to a SQL database based metadata storage, like MySql, SqlServer.
For example, connect to MySql or SqlServer by set environment variables:
set AZURITE_DB=mysql://username:password@localhost:3306/azurite_blob
set AZURITE_DB=mssql://username:password@localhost:1024/azurite_blob
When Azurite starts with above environment variable, it connects to the configured database, and creates tables if not exist.
This feature is in preview, when Azurite changes database table schema, you need to drop existing tables and let Azurite regenerate database tables.
Note. Need to manually create database before starting Azurite instance.
Note. Blob Copy & Page Blob are not supported by SQL based metadata implementation.
Tips. Create database instance quickly with docker, for example docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:latest
. Grant external access and create database azurite_blob
using docker exec mysql mysql -u root -pmy-secret-pw -e "GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; FLUSH PRIVILEGES; create database azurite_blob;"
. Notice that, above commands are examples, you need to carefully define the access permissions in your production environment.
HTTPS Setup
Azurite natively supports HTTPS with self-signed certificates via the --cert
and --key
/--pwd
options. You have two certificate type options: PEM or PFX. PEM certificates are split into "cert" and "key" files. A PFX certificate is a single file that can be assigned a password.
PEM
Generate PEM Certificate and Key
You have a few options to generate PEM certificate and key files. We'll show you how to use mkcert and OpenSSL.
mkcert
mkcert is a utility that makes the entire self-signed certificate process much easier because it wraps a lot of the complex commands that you need to manually execute with other utilities.
Generate Certificate and Key with mkcert
- Install mkcert: https://github.com/FiloSottile/mkcert#installation. We like to use choco
choco install mkcert
, but you can install with any mechanism you'd like. - Run the following commands to install the Root CA and generate a cert for Azurite.
mkcert -install
mkcert 127.0.0.1
That will create two files. A certificate file: 127.0.0.1.pem
and a key file: 127.0.0.1-key.pem
.
Start Azurite with HTTPS and PEM
Then you start Azurite with that cert and key.
azurite --cert 127.0.0.1.pem --key 127.0.0.1-key.pem
If you start Azurite with docker, you need to map the folder contains the cert and key files to docker.
In following example, the local folder c:/azurite contains the cert and key files, and map it to /workspace on docker.
docker run -p 10000:10000 -p 10001:10001 -p 10002:10002 -v c:/azurite:/workspace mcr.microsoft.com/azure-storage/azurite azurite --blobHost 0.0.0.0 --queueHost 0.0.0.0 --tableHost 0.0.0.0 --cert /workspace/127.0.0.1.pem --key /workspace/127.0.0.1-key.pem
OpenSSL
OpenSSL is a TLS/SSL toolkit. You can use it to generate certificates. It is more involved than mkcert, but has more options.
Install OpenSSL on Windows
- Download and install the OpenSSL v1.1.1a+ EXE from http://slproweb.com/products/Win32OpenSSL.html
- Set the following environment variables
set OPENSSL_CONF=c:\OpenSSL-Win32\bin\openssl.cfg
set Path=%PATH%;c:\OpenSSL-Win32\bin
Generate Certificate and Key
Execute the following command to generate a cert and key with OpenSSL.
openssl req -newkey rsa:2048 -x509 -nodes -keyout key.pem -new -out cert.pem -sha256 -days 365 -addext "subjectAltName=IP:127.0.0.1" -subj "/C=CO/ST=ST/L=LO/O=OR/OU=OU/CN=CN"
The -subj
values are required, but do not have to be valid. The subjectAltName
must contain the Azurite IP address.
Add Certificate to Trusted Root Store
You then need to add that certificate to the Trusted Root Certification Authorities. This is required to work with Azure SDKs and Storage Explorer.
Here's how to do that on Windows:
certutil –addstore -enterprise –f "Root" cert.pem
Start Azurite with HTTPS and PEM
Then you start Azurite with that cert and key.
Azurite --cert cert.pem --key key.pem
NOTE: If you are using the Azure SDKs, then you will also need to pass the --oauth basic
option.
PFX
Generate PFX Certificate
You first need to generate a PFX file to use with Azurite.
You can use the following command to generate a PFX file with dotnet dev-certs
, which is installed with the .NET Core SDK.
dotnet dev-certs https --trust -ep cert.pfx -p <password>
Storage Explorer does not currently work with certificates produced by dotnet dev-certs
. While you can use them for Azurite and Azure SDKs, you won't be able to access the Azurite endpoints with Storage Explorer if you are using the certs created with dotnet dev-certs. We are tracking this issue on GitHub here: https://github.com/microsoft/AzureStorageExplorer/issues/2859
Start Azurite with HTTPS and PFX
Then you start Azurite with that cert and key.
azurite --cert cert.pem --key key.pem
NOTE: If you are using the Azure SDKs, then you will also need to pass the --oauth basic
option.
Start Azurite
Usage with Azure Storage SDKs or Tools
Default Storage Account
Azurite V3 provides support for a default storage account as General Storage Account V2 and associated features.
- Account name:
devstoreaccount1
- Account key:
Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
Note. Besides SharedKey authentication, Azurite V3 supports account, OAuth, and service SAS authentication. Anonymous access is also available when container is set to allow public access.
Customized Storage Accounts & Keys
As mentioned by above section. Azurite V3 allows customizing storage account names and keys by providing environment variable AZURITE_ACCOUNTS
with format account1:key1[:key2];account2:key1[:key2];...
.
For example, customize one storage account which has only one key:
set AZURITE_ACCOUNTS="account1:key1"
Or customize multi storage accounts and each has 2 keys:
set AZURITE_ACCOUNTS="account1:key1:key2;account2:key1:key2"
Connection Strings
HTTP Connection Strings
You can pass the following connection strings to the Azure SDKs or tools (like Azure CLI 2.0 or Storage Explorer)
The full connection string is:
DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=http://127.0.0.1:10001/devstoreaccount1;TableEndpoint=http://127.0.0.1:10002/devstoreaccount1;
Take blob service only, the full connection string is:
DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;
Or if the SDK or tools support following short connection string:
UseDevelopmentStorage=true;
HTTPS Connection Strings
The full HTTPS connection string is:
DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=https://127.0.0.1:10001/devstoreaccount1;
To use the Blob service only, the HTTPS connection string is:
DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;
If you used dotnet dev-certs
to generate your self-signed certificate, then you need to use the following connection string, because that only generates a cert for localhost
, not 127.0.0.1
.
DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=https://localhost:10000/devstoreaccount1;QueueEndpoint=https://localhost:10001/devstoreaccount1;
Azure SDKs
To use Azurite with the Azure SDKs, you can use OAuth with HTTPS options:
azurite --oauth basic --cert certname.pem --key certname-key.pem
Azure Blob Storage
You can then instantiate BlobContainerClient, BlobServiceClient, or BlobClient.
var client = new BlobContainerClient(new Uri("https://127.0.0.1:10000/devstoreaccount1/container-name"), new DefaultAzureCredential());
var client = new BlobContainerClient("DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=https://127.0.0.1:10001/devstoreaccount1;", "container-name");
var client = new BlobContainerClient(new Uri("https://127.0.0.1:10000/devstoreaccount1/container-name"), new StorageSharedKeyCredential("devstoreaccount1", "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="));
Azure Queue Storage
You can also instantiate QueueClient or QueueServiceClient.
var client = new QueueClient(new Uri("https://127.0.0.1:10001/devstoreaccount1/queue-name"), new DefaultAzureCredential());
var client = new QueueClient("DefaultEndpointsProtocol=https;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=https://127.0.0.1:10000/devstoreaccount1;QueueEndpoint=https://127.0.0.1:10001/devstoreaccount1;", "queue-name");
var client = new QueueClient(new Uri("https://127.0.0.1:10001/devstoreaccount1/queue-name"), new StorageSharedKeyCredential("devstoreaccount1", "Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="));
Storage Explorer
Storage Explorer with Azurite HTTP
Connect to Azurite by click "Add Account" icon, then select "Attach to a local emulator" and click "Connect".
Storage Explorer with Azurite HTTPS
By default Storage Explorer will not open an HTTPS endpoint that uses a self-signed certificate. If you are running Azurite with HTTPS, then you are likely using a self-signed certificate. Fortunately, Storage Explorer allows you to import SSL certificates via the Edit -> SSL Certificates -> Import Certificates dialog.
Import Certificate to Storage Explorer
- Find the certificate on your local machine.
- OpenSSL: You can find the PEM file at the location you created in the HTTPS Setup section above.
- mkcert: You need to import the RootCA.pem file, which can be found by executing this command in the terminal:
mkcert -CAROOT
. For mkcert, you want to import the RootCA.pem file, not the certificate file you created. - dotnet dev-certs: Storage Explorer doesn't currently work with certs produced by
dotnet dev-certs
. We are tracking this issue on GitHub here: https://github.com/microsoft/AzureStorageExplorer/issues/2859
- Open Storage Explorer -> Edit -> SSL Certificates -> Import Certificates and import your certificate.
If you do not set this, then you will get the following error:
unable to verify the first certificate
or
self signed certificate in chain
Add Azurite via HTTPS Connection String
Follow these steps to add Azurite HTTPS to Storage Explorer:
- Right click on Local & Attached -> Storage Accounts and select "Connect to Azure Storage...".
- Select "Use a connection string" and click Next.
- Enter a name, i.e Azurite.
- Enter the HTTPS connection string from the previous section of this document and click Next.
You can now explore the Azurite HTTPS endpoints with Storage Explorer.

Note. Delete above files and folders and restart Azurite to clean up Azurite. It will remove all data stored in Azurite!!
Differences between Azurite and Azure Storage
Because Azurite runs as a local instance for persistent data storage, there are differences in functionality between Azurite and an Azure storage account in the cloud.
Storage Accounts
Please reach to us or open issues if you need multi storage account support.
Azurite V3 supports a default account as General Storage Account V2 and provides features.
- Account name:
devstoreaccount1
- Account key:
Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
Endpoint & Connection URL
The service endpoints for Azurite are different from those of an Azure storage account. The difference is because the local computer does not perform domain name resolution, requiring Azurite endpoints to be local addresses.
When you address a resource in an Azure storage account, use the following scheme. The account name is part of the URI host name, and the resource being addressed is part of the URI path:
<http|https>://<account-name>.<service-name>.core.windows.net/<resource-path>
For example, the following URI is a valid address for a blob in an Azure storage account:
https://myaccount.blob.core.windows.net/mycontainer/myblob.txt
However, because the local computer does not perform domain name resolution, the account name is part of the URI path instead of the host name. Use the following URI format for a resource in Azurite:
http://<local-machine-address>:<port>/<account-name>/<resource-path>
For example, the following address might be used for accessing a blob in Azurite:
http://127.0.0.1:10000/myaccount/mycontainer/myblob.txt
The service endpoints for Azurite blob service:
http://127.0.0.1:10000/<account-name>/<resource-path>
Scalability & Performance
Please reach to us if you have requirements or suggestions for a distributed Azurite implementation or higher performance.
Azurite is not a scalable storage service and does not support many concurrent clients. There is also no performance and TPS guarantee, they highly depend on the environments Azurite has deployed.
Error Handling
Please reach to us if you have requirements or suggestions for a specific error handling.
Azurite tries to align with Azure Storage error handling logic, and provides best-efforts alignment based on Azure Storage online documentation. But CANNOT provide 100% alignment, such as error messages (returned in error response body) maybe different (while error status code will align).
API Version Compatible Strategy
Azurite V3 follows a Try best to serve compatible strategy with Azure Storage API versions:
- An Azurite V3 instance has a baseline Azure Storage API version.
- A Swagger definition (OpenAPI doc) with the same API version will be used to generate protocol layer APIs and interfaces.
- Azurite should implement all the possible features provided in this API service version.
- If an incoming request has the same API version Azurite provides, Azurite should handle the request with parity to Azure Storage.
- If an incoming request has a higher API version than Azurite, Azurite will return a InvalidHeaderValue error for
x-ms-version
(HTTP status code 400 - Bad Request). - If an incoming request has a lower API version header than Azurite, Azurite will attempt to handle the request with Azurite's baseline API version behavior instead of that specified in the request.
- Azurite will return API version in response header as the baseline API version
- SAS accepts pattern from API version 2015-04-05
RA-GRS
Azurite supports read-access geo-redundant replication (RA-GRS). For storage resources both in the cloud and in the local emulator, you can access the secondary location by appending -secondary to the account name. For example, the following address might be used for accessing a blob using the secondary in Azurite:
http://127.0.0.1:10000/devstoreaccount1-secondary/mycontainer/myblob.txt
Note. Secondary endpoint is not read-only in Azurite, which diffs from Azure Storage.
Differences between Azurite V3 and Azurite V2
Both Azurite V3 and Azurite V2 aim to provide a convenient emulation for customers to quickly try out Azure Storage services locally. There are lots of differences between Azurite V3 and legacy Azurite V2.
Architecture
Architecture in Azurite V3 has been refactored, it's more flexible and robust. It provides the flexibility to support following scenarios in the future:
- Use other HTTP frameworks instead of express.js
- Customized new handler layer implementation, such as redirecting requests to Azure Storage services
- Implement and inject a new persistency layer implementation, such as one based on a different database service
- Provide support for multiple azure storage accounts and authentication
- Detailed debug logging for easy issue investigation and request tracking
- Create HTTPS server
- ...
Server Code Generator
Azurite V3 leverages a TypeScript server code generator based on Azure Storage REST API swagger specifications. This reduces manual efforts and ensures alignment with the API implementation.
TypeScript
Azurite V3 selected TypeScript as its' programming language, as this facilitates broad collaboration, whilst also ensuring quality.
Features Scope
Legacy Azurite V2 supports Azure Storage Blob, Queue and Table services.
Azurite V3 currently only supports Azure Storage blob service. Queue service is supported after V3.2.0-preview.
Table service support is currently under discussion.
Azurite V3 supports features from Azure Storage API version 2020-10-02, and will maintain parity with the latest API versions, in a more frequent update frequency than legacy Azurite V2.
TypeScript Server Code Generator
Azurite V3 leverages a TypeScript Node.js Server Code Generator to generate the majority of code from Azure Storage REST APIs swagger specification.
Currently, the generator project is private, under development and only used by Azurite V3.
We have plans to make the TypeScript server generator public after Azurite V3 releases.
All the generated code is kept in generated
folder, including the generated middleware, request and response models.
