Develop Apps Script projects locally using clasp (Command Line Apps Script Projects).
To get started, try out the codelab!
🗺️ Develop Locally: clasp allows you to develop your Apps Script projects locally. That means you can check-in your code into source control, collaborate with other developers, and use your favorite tools to develop Apps Script.
🔢 Manage Deployment Versions: Create, update, and view your multiple deployments of your project.
📁 Structure Code: clasp automatically converts your flat project on script.google.com into folders. For example:
tests/slides.gstests/sheets.gstests/
slides.jssheets.js🔷 Write Apps Script in TypeScript: Write your Apps Script projects using TypeScript features:
➡️ Run Apps Script: Execute your Apps Script from the command line. Features:
First download clasp:
sudo npm i @google/clasp -g
# Alternatively: sudo npm i -g grpc @google/clasp --unsafe-perm
Then enable the Google Apps Script API: https://script.google.com/home/usersettings
The following command provide basic Apps Script project management.
Note: Most of them require you to
clasp loginandclasp create/clonebefore using the rest of the commands.

Steps:
.claspignore in your project's root directory.clasp push. Note: The .claspignore patterns are applied by multimatch, which is different from .gitignore, especially for directories. To ignore a directory, use syntax like **/node_modules/**.A sample .claspignore ignoring everything except the manifest and build/main.js:
**/**
!build/main.js
!appsscript.json
Note: The .claspignore patterns are applied relative from the rootDir.
If no .claspignore is specified, a default set of patterns is applied. The default will only consider the appsscript.json manifest and any JavaScript and TypeScript source files in the rootDir folder
**/**
!appsscript.json
!*.gs
!*.js
!*.ts
!*.html
.clasp.json)When running clone or create, a file named .clasp.json is created in the current directory to describe clasp's configuration for the current project. Example .clasp.json:
{
"scriptId": "",
"rootDir": "build/",
"projectId": "project-id-xxxxxxxxxxxxxxxxxxx",
"fileExtension": "ts",
"filePushOrder": ["file1.ts", "file2.ts"]
}
The following configuration values can be used:
scriptId (required)Specifies the id of the Google Script project that clasp will target. It is the part located inbetween /d/ and /edit in your project's URL: https://script.google.com/d/<SCRIPT_ID>/edit.
rootDir (optional)Specifies the local directory in which clasp will store your project files. If not specified, clasp will default to the current directory.
projectId (optional)Specifies the id of the Google Cloud Platform project that clasp will target. You must associate Google Script project with Google Cloud Platform beforehand.
clasp open.Resources > Cloud Platform project....project-id-xxxxxxxxxxxxxxxxxxx.Even if you do not set this manually, clasp will ask this via a prompt to you at the required time.
fileExtension (optional)Specifies the file extension for local script files in your Apps Script project.
filePushOrder (optional)Specifies the files that should be pushed first, useful for scripts that rely on order of execution. All other files are pushed after this list of files.
The library requires Node version >= 6.3.0. Use this script to check your version and upgrade Node if necessary:
node -v # Check Node version
sudo npm install n -g
sudo n latest
Clasp supports proxies via the Google APIs Node Module.
See "Using a Proxy" and this discussion for details on how to use the proxy.
This requires using the environment variables HTTP_PROXY / HTTPS_PROXY.
