google-cloud-bucket
Advanced tools
Google Cloud Bucket is a node.js package to manage Google Cloud Buckets and its objects. All read APIs uses an exponential backoff retry strategy in cases of errors. By default, that strategy times out after 10 seconds, but it can be configured.
npm i google-cloud-bucket --save
Before using this package, you must first:
Have a Google Cloud Account.
Have a Service Account set up with the following 2 roles:
roles/storage.objectCreatorroles/storage.objectAdmin (only if you want to update access to object or create/delete buckets)roles/storage.admin (only if you want to update access to an entire bucket)Get the JSON keys file for that Service Account above
Save that JSON key into a service-account.json file. Make sure it is located under a path that is accessible to your app (the root folder usually).
const { join } = require('path')
const { client } = require('google-cloud-bucket')
const storage = client.new({
jsonKeyFile: join(__dirname, './service-account.json')
})
// LISTING ALL THE BUCKETS IN THAT PROJECT
storage.list().then(console.log)
const someObject = {
firstname: 'Nicolas',
lastname: 'Dao',
company: 'Neap Pty Ltd',
city: 'Sydney'
}
// CREATING A BUCKET (This method will fail if your bucket name is not globally unique. You also need to the role 'roles/storage.objectAdmin')
storage.bucket('your-globally-unique-bucket-name').create()
.then(data => console.log(data))
// CREATING A BUCKET IN SPECIFIC LOCATION (default is US. A detailed list of all the locations can be found in the Annexes of this document)
storage.bucket('your-globally-unique-bucket-name').create({ location: 'australia-southeast1' })
.then(data => console.log(data))
// DELETING A BUCKET
storage.bucket('your-globally-unique-bucket-name').delete({ force:true })
.then(data => console.log(data))
// GET A BUCKET'S SETUP DATA
storage.bucket('your-globally-unique-bucket-name').get()
.then(data => console.log(data))
// ADDING AN OBJECT
storage.insert(someObject, 'your-bucket/a-path/filename.json') // insert an object into a bucket 'a-path/filename.json' does not need to exist
.then(() => storage.get('your-bucket/a-path/filename.json')) // retrieve that new object
.then(res => console.log(JSON.stringify(res, null, ' ')))
// ADDING A HTML PAGE WITH PUBLIC ACCESS (warning: Your service account must have the 'roles/storage.objectAdmin' role)
const html = `
<!doctype html>
<html>
<body>
<h1>Hello Giiiiirls</h1>
</body>
</html>`
storage.insert(html, 'your-bucket/a-path/index.html')
// UPLOADING AN IMAGE (we assume we have access to an image as a buffer variable called 'imgBuffer')
storage.insert(imgBuffer, 'your-bucket/a-path/image.jpg')
// GETTING BACK THE OBJECT
storage.get('your-bucket/a-path/filename.json').then(obj => console.log(obj))
// GETTING THE HTML BACK
storage.get('your-bucket/a-path/index.html').then(htmlString => console.log(htmlString))
// GETTING BACK THE IMAGE
// USE CASE 1 - Loading the entire buffer in memory
storage.get('your-bucket/a-path/image.jpg').then(imgBuffer => console.log(imgBuffer))
// USE CASE 2 - Loading the image on your filesystem
storage.get('your-bucket/a-path/image.jpg', { dst: 'some-path/image.jpg' })
.then(() => console.log(`Image successfully downloaded.`))
// USE CASE 3 - Piping the image buffer into a custom stream reader
const { Writable } = require('stream')
const customReader = new Writable({
write(chunk, encoding, callback) {
console.log('Hello chunk of image')
callback()
}
})
storage.get('your-bucket/a-path/image.jpg', { streamReader: customReader })
.then(() => console.log(`Image successfully downloaded.`))
// TESTING IF A FILE OR A BUCKET EXISTS
storage.exists('your-bucket/a-path/image.jpg')
.then(fileExists => fileExists ? console.log('File exists.') : console.log('File does not exist.'))
// LISTING ALL THE FILES METADATA WITH A FILEPATH THAT STARTS WITH SPECIFIC NAME
storage.list('your-bucket/a-path/')
.then(files => console.log(files))
Bucket API
The examples above demonstrate how to insert and query any storage. We've also included a variant of those APIs that are more focused on the bucket:
// THIS API:
storage.insert(someObject, 'your-bucket/a-path/filename.json')
// CAN BE REWRITTEN AS FOLLOW:
storage.bucket('your-bucket').object('a-path/filename.json').insert(someObject)
// THIS API:
storage.get('your-bucket/a-path/filename.json').then(obj => console.log(obj))
// CAN BE REWRITTEN AS FOLLOW:
storage.bucket('your-bucket').object('a-path/filename.json').get().then(obj => console.log(obj))
// THIS API:
storage.exists('your-bucket/a-path/image.jpg')
.then(fileExists => fileExists ? console.log('File exists.') : console.log('File does not exist.'))
// CAN BE REWRITTEN AS FOLLOW:
storage.bucket('your-bucket').object('a-path/image.jpg').exists()
.then(fileExists => fileExists ? console.log('File exists.') : console.log('File does not exist.'))
// THIS API:
storage.list('your-bucket/a-path/')
.then(files => console.log(files))
// CAN BE REWRITTEN AS FOLLOW:
storage.bucket('your-bucket').object('a-path/').list()
.then(files => console.log(files))
This allows to make any files publicly readable by anybody on the web. That's usefull if you want to host a website, or publish data (e.g., RSS feed).
Once your bucket is publicly readable, everyone can access it at this url: https://storage.googleapis.com/your-bucket/some-path/index.html
WARNING: If that bucket hosts files that hsould be accessible cross domain (e.g., an RSS feed), don't forget to also set up CORS (next section Configuring CORS On a Bucket).
const bucket = storage.bucket('your-bucket')
// TEST WHETHER A BUCKET IS PUBLIC OR NOT
bucket.isPublic().then(isPublic => isPublic ? console.log(`Bucket '${bucket.name}' is public`) : console.log(`Bucket '${bucket.name}' is not public`))
// MAKING A BUCKET PUBLICLY READABLE (warning: Your service account must have the 'roles/storage.admin' role)
// Once a bucket is public, all content added to it (even when omitting the 'public' flag) is public
bucket.addPublicAccess()
.then(({ publicUri }) => console.log(`Your web page is publicly available at: ${publicUri}`))
// REMOVING THE PUBLICLY READABLE ACCESS FROM A BUCKET (warning: Your service account must have the 'roles/storage.admin' role)
bucket.removePublicAccess()
// MAKING AN EXISTING OBJECT PUBLICLY READABLE (warning: Your service account must have the 'roles/storage.objectAdmin' role)
bucket.object('a-path/private.html').addPublicAccess()
.then(({ publicUri }) => console.log(`Your web page is publicly available at: ${publicUri}`))
// REMOVING THE PUBLICLY READABLE ACCESS FROM A FILE (warning: Your service account must have the 'roles/storage.objectAdmin' role)
bucket.object('a-path/private.html').removePublicAccess()
It is also possible to make a single file publicly readable in a single command when the file is created:
storage.insert(html, 'your-bucket/a-path/index.html', { public: true })
.then(({ publicUri }) => console.log(`Your web page is publicly available at: ${publicUri}`))
Once your file is publicly readable, everyone can access it at this url: https://storage.googleapis.com/your-bucket/a-path/index.html
WARNING: If that bucket hosts files that hsould be accessible cross domain (e.g., an RSS feed), don't forget to also set up CORS (next section Configuring CORS On a Bucket).
It is also possible to set a file's content encoding in a single command when the file is created:
storage.insert(html, 'your-bucket/a-path/index.html', { contentEncoding: 'gzip' })
.then(({ publicUri }) => console.log(`Your gzipped file is available at: ${publicUri}`))
If your files are publicly readable on the web, they might not be accessible when referenced from other websites. To enable other websites to access your files, you will have to configure CORS on your bucket:
// CONFIGURE CORS ON A BUCKET (warning: Your service account must have the 'roles/storage.admin' role)
bucket.cors.setup({
origin: ['*'],
method: ['GET', 'OPTIONS', 'HEAD', 'POST'],
responseHeader: ['Authorization', 'Origin', 'X-Requested-With', 'Content-Type', 'Accept'],
maxAgeSeconds: 3600
})
.then(() => console.log(`CORS successfully set up on your bucket.`))
If you want to check if CORS has already been set up on a bucket:
bucket.cors.exists().then(yes => yes
? console.log(`CORS already set up on bucket '${bucket.name}'.`)
: console.log(`CORS not set up yet on bucket '${bucket.name}'.`))
You can also check if a specific CORS config exists:
bucket.cors.exists({
origin: ['*'],
method: ['GET', 'OPTIONS', 'HEAD', 'POST'],
responseHeader: ['Authorization', 'Origin', 'X-Requested-With', 'Content-Type', 'Accept'],
maxAgeSeconds: 3600
}).then(yes => yes
? console.log(`CORS already set up on bucket '${bucket.name}'.`)
: console.log(`CORS not set up yet on bucket '${bucket.name}'.`))
To remove CORS from a bucket:
bucket.cors.disable().then(() => console.log(`CORS successfully disabled on bucket '${bucket.name}'.`))
To achieve this you need to setup 5 things:
You need to setup the service account that you've been using to manage your bucket (defined in your service-account.json) as a domain owner. To achieve that, the first step is to prove your ownership using https://search.google.com/search-console/welcome. When that's done, open the settings and select User and permissions. There, you'll be able to add a new owner, which will allow you to add the email of your service account.
Create a bucket with a name matching your domain (e.g., www.your-domain-name.com)
Make that bucket public. Refer to section Publicly Readable Config above.
Add a new CNAME record in your DNS similar to this:
| Type | Name | Value |
|---|---|---|
| CNAME | www | c.storage.googleapis.com |
Configure the bucket so that each index.html and the 404.html page are the default pages (otherwise, you'll have to explicitly enter http://www.your-domain-name.com/index.html to reach your website instead of simply entering http://www.your-domain-name.com):
bucket.website.setup({
mainPageSuffix: 'index.html',
notFoundPage: '404.html'
}).then(console.log)
const bucket = storage.bucket('your-bucket-name')
bucket.object('some-folder-path').zip({
to: {
local: 'some-path-on-your-local-machine',
bucket: {
name: 'another-existing-bucket-name', // Optional (default: Source bucket. In our example, that source bucket is 'your-bucket-name')
path: 'some-folder-path.zip' // Optional (default: 'archive.zip'). If specified, must have the '.zip' extension.
}
},
ignore:[/\.png$/, /\.jpg$/, /\.html$/] // Optional. Array of strings or regex
})
.then(({ count, data }) => {
console.log(`${count} files have been zipped`)
if (data)
// 'data' is null if the 'options.to' is defined
console.log(`The zip file's size is: ${data.length/1024} KB`)
})
Extra Options
You can also track the various steps of the zipping process with the optional on object:
const bucket = storage.bucket('your-bucket-name')
bucket.object('some-folder-path').zip({
to: {
local: 'some-path-on-your-local-machine',
bucket: {
name: 'another-existing-bucket-name', // Optional (default: Source bucket. In our example, that source bucket is 'your-bucket-name')
path: 'some-folder-path.zip' // Optional (default: 'archive.zip'). If specified, must have the '.zip' extension.
}
},
on:{
'files-listed': (files) => {
console.log(`Total number of files to be zipped: ${files.count}`)
console.log(`Raw size: ${(files.size/1024/1024).toFixed(1)} MB`)
// 'files.data' is an array of all the files' details
},
'file-received': ({ file, size }) => {
console.log(`File ${file} (byte size: ${size}) is being zipped`)
},
'finished': ({ size }) => {
console.log(`Zip process completed. The zip file's size is ${size} bytes`)
},
'saved': () => {
console.log('The zipped file has been saved')
},
'error': err => {
console.log(`${err.message}\n${err.stack}`)
}
}
})
.then(({ count, data }) => {
console.log(`${count} files have been zipped`)
if (data)
// 'data' is null if the 'options.to' is defined
console.log(`The zip file's size is: ${data.length/1024} KB`)
})
service-account.jsonWe assume that you have created a Service Account in your Google Cloud Account (using IAM) and that you've downloaded a service-account.json (the name of the file does not matter as long as it is a valid json file). The first way to create a client is to provide the path to that service-account.json as shown in the following example:
const storage = client.new({
jsonKeyFile: join(__dirname, './service-account.json')
})
This method is similar to the previous one. You should have dowloaded a service-account.json, but instead of providing its path, you provide some of its details explicitly:
const storage = client.new({
clientEmail: 'some-client-email',
privateKey: 'some-secret-private-key',
projectId: 'your-project-id'
})
If you're managing an Google Cloud OAuth2 token yourself (most likely using the google-auto-auth library), you are not required to explicitly pass account details like what was done in the previous 2 approaches. You can simply specify the projectId:
const storage = client.new({ projectId: 'your-project-id' })
Refer to the next section to see how to pass an OAuth2 token.
Networks errors (e.g. socket hang up, connect ECONNREFUSED) are a fact of life. To deal with those undeterministic errors, this library uses a simple exponential back off retry strategy, which will reprocess your read or write request for 10 seconds by default. You can increase that retry period as follow:
// Retry timeout for CHECKING FILE EXISTS
storage.exists('your-bucket/a-path/image.jpg', { timeout: 30000 }) // 30 seconds retry period timeout
// Retry timeout for INSERTS
storage.insert(someObject, 'your-bucket/a-path/filename.json', { timeout: 30000 }) // 30 seconds retry period timeout
// Retry timeout for QUERIES
storage.get('your-bucket/a-path/filename.json', { timeout: 30000 }) // 30 seconds retry period timeout
If you've used the 3rd method to create a client (i.e. 3. Using a ProjectId), then all the method you use require an explicit OAuth2 token:
storage.list({ token }).then(console.log)
All method accept a last optional argument object.
The Google Cloud Storage API supports partial response. This allows to only return specific fields rather than all of them, which can improve performances if you're querying a lot of objects. The only method that currently supports partial response is the the list API.
storage.bucket('your-bucket').object('a-folder/').list({ fields:['name'] })
The above example only returns the name field. The full list of supported fields is detailed under bucketObject.list([options]) section.

This URI follows this structure: https://storage.googleapis.com/your-bucket-id/your-file-path.Follow those rules to choose a bucket's name (those rules were extracted from the official Google Cloud Storage documentation):
To help validate if a name follows those rules, this package provides a utility method called validate.bucketName:
const { utils:{ validate } } = require('google-cloud-bucket')
const validate.bucketName('hello') // => { valid:true, reason:null }
validate.bucketName('hello.com') // => { valid:true, reason:null }
validate.bucketName('he_llo-23') // => { valid:true, reason:null }
validate.bucketName('_hello') // => { valid:false, reason:'The bucket name must start and end with a number or letter.' }
validate.bucketName('hEllo') // => { valid:false, reason:'The bucket name must contain only lowercase letters, numbers, dashes (-), underscores (_), and dots (.).' }
validate.bucketName('192.168.5.4') // => { valid:false, reason:'The bucket name cannot be represented as an IP address in dotted-decimal notation (for example, 192.168.5.4).' }
validate.bucketName('googletest') // => { valid:false, reason:'The bucket name cannot begin with the "goog" prefix or contain close misspellings, such as "g00gle".' }
Single reagions are bucket locations that indicate that your data are replicated in multiple servers in that single region. Though it is unlikely that you would loose your data because all servers fail, it is however possible that a network failure brings that region inaccessbile. At this stage, your data would not be lost, but they would be unavailable for the period of that network outage. This type of storage is the cheapest.
Use this type of location if your data:
If the above limits are too strict for your use case, then you should probably use a Multi Regions.
