@bigbangjs/file-storage-s3 NPM

💥 BigBangJS File Storage - AWS S3 Provider

AWS S3 provider for @bigbangjs/file-storage.

External/Peer dependencies:

This package includes aws-sdk as a dependency. You don't have to install it by yourself

🚀 Quick start

Install the package using npm or yarn

$ npm i @bigbangjs/file-storage-s3
# or
$ yarn add @bigbangjs/file-storage-s3

Register the provider globally in the storage

import {S3Provider} from '@bigbangjs/file-storage-s3;

FileStorage.registerProviderType('s3', S3Provider);

Init the Storage and add a provider instance and buckets

import {FileStorage} from '@bigbangjs/file-storage';
import { S3BucketConfig, S3Provider, S3ProviderConfig } from '@bigbangjs/file-storage-s3';

// create a storage insance [FileStorageConfigOptions]
const storage = new FileStorage({
    defaultBucketMode: '0777',
    bucketAliasStrategy: 'NAME',
    autoInitProviders: true,
    autoCleanup: true,
    defaultBucketName: 'mybucket',
    returningByDefault: false,,
    logger: console,
});

// add a provider
const myProvider=(await storage.addProvider({
    uri: 's3://<pathToCredentilsFile>',
    name: 'myprovider'
})).result;

// add a bucket using object config
const myBucket=(await myProvider.addBucket({ bucketName: 's3BucketName', name:'bucket01' }));

// add a bucket using url object
const myBucket=(await myProvider.addBucket({ uri: 'myprovider://s3BucketName?name=bucket02' }));

// add a bucket using url string
const myBucket=(await myProvider.addBucket('myprovider://s3BucketName?name=bucket03'));

// the bucket is ready to use, for example, create a file
const fileUri= (await myBucket.putFile('directory/test.txt', 'Hello world!')).result;
//the response will be: myprovider://bucket01/directory/test.txt

💥 Provider configuration options

You can set the configuration of the provider as an "url" or a S3ProviderConfig object.

The url must be in the form:

<providerTypeName>://<pathToCredentialsFile>?name=<providerName>&projectId=<s3ProjectId>[&mode=0777][&signedUrlExpiration=3600][&tryCreateBuckets=true|false][&useNativeUrlGenerator=true|false][&autoRetry=true|false][&maxRetries=true|false][&userAgent=string][&apiEndpoint=string]

The configuration object can have the following properties:

{
    // the name of the provider (required)
    name: string;
    // the root path in the filesystem (required)
    root: string;
    // write/read mode in octal or string format [default:'0777']
    mode?: string | number;
    // delete empty directories (recommended) [default:true]
    autoCleanup?: boolean;
    // signed url expiration (in seconds) [default:3600]
    defaultSignedUrlExpiration?: number;
    // buckets (will be added when the `init` method gets called)
    buckets?: (Partial<FileSystemBucketConfig> | string)[];
    // uri (optional) you can pass an uri as config
    uri?:string;

    // path to the credentials.json
    keyFile?:string;

💥 Bucket configuration options

You can set the configuration of the provider as an "url" or a S3BucketConfig object.

The url must be in the form:

<providerName>://<pathToRoot>?name=<localBucketName>&bucketName=<bucketNameAsIsInGoogleCloudStorage>[&mode=0777][&signedUrlExpiration=3600][&tryCreate=true|false]

The configuration object can have the following properties:

{
    // the name of the bucket (required)
    name: string;
    // bucket name as appears in Google Cloud Storage (required)
    bucketName: string;
    // try create the bucket in S3 if doesn't exist? [default: the provider value]
    tryCreate?: boolean;
    // uri (optional) you can pass an uri as config
    uri?: string;
    // the name of the provider (this is required when you add the bucket directly to the storage instance, not when you add it to the provider instance)
    providerName?: string;
    // write/read mode in octal or string format [default:'0777']
    mode?: string | number;
    // signed url expiration (in seconds) [default:3600]
