Google Cloud Bucket is node.js package to add objects to a Google Cloud Bucket.
npm i google-cloud-bucket --save
Before using this package, you must first:
Have a Google Cloud Account.
Have a bucket in that Google 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)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')
})
const someObject = {
firstname: 'Nicolas',
lastname: 'Dao',
company: 'Neap Pty Ltd',
city: 'Sydney'
}
// ADDING AN OBJECT WITH PRIVATE ACCESS
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', { public: true })
.then(({ publicUri }) => console.log(`Your web page is publicly available at: ${publicUri}`))
// 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.`))
Notice the usage of the
public: trueflag in theinsertstatement above. This automatically makes this specific file publicly available at https://storage.googleapis.com/your-bucket/a-path/index.html. If that file is supposed to stay private, then don't use that flag. To make the entire bucket public, refer to the next section Publicly Readable Config.
The examples above show how to insert and query any storage. We've also included a variant of those APIs that are more focused on a specific bucket:
// THIS API
storage.insert(someObject, 'your-bucket/a-path/filename.json')
// CAN BE REWRITTEN
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
storage.bucket('your-bucket').object('a-path/filename.json').get().then(obj => console.log(obj))
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).
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: ${publicUri}`))
// REMOVING THE PUBLICLY READABLE ACCESS FROM A FILE (warning: Your service account must have the 'roles/storage.objectAdmin' role)
bucket.object('a-path/private.html').removePublicAccess()
If your files are publicly readable on the web, they might not be accessible when referenced from other websites. To enable other websites to access your files, you will have to configure CORS on your bucket:
// CONFIGURE CORS ON A BUCKET (warning: Your service account must have the 'roles/storage.admin' role)
bucket.cors.setup({
origin: ['*'],
method: ['GET', 'OPTIONS', 'HEAD', 'POST'],
responseHeader: ['Authorization', 'Origin', 'X-Requested-With', 'Content-Type', 'Accept'],
maxAgeSeconds: 3600
})
.then(() => console.log(`CORS successfully set up on your bucket.`))
If you want to check if CORS has already been set up on a bucket:
bucket.cors.exists().then(yes => yes
? console.log(`CORS already set up on bucket '${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}'.`))
