A file system abstraction for Node.js     |___/

A simple abstraction to interact with file system inspired by Laravel File System, provide one interface for many kind of drivers: local, ftp, sftp, Amazon S3, and Google Cloud Storage, even your custom driver.

Installation

$ yarn add @file-storage/core @file-storage/common

# Or npm
$ npm install @file-storage/core @file-storage/common

And upload a file to local, it will be stored in storage folder in your root project directory by default:

import Storage from '@file-storage/core';

// Upload from file path.
Storage.put('/my-image.png', '/path/of/destination/my-image.png');

// Or from a read-stream/buffer:
Storage.put(stream, '/path/of/destination/my-image.png');

Configuration

By default only local driver is supported, if you want to use another driver, you need to install corresponding package:

• Amazon S3: yarn add @file-storage/s3
• FTP: yarn add @file-storage/ftp
• SFTP: yarn add @file-storage/sftp
• Google Cloud Storage: yarn add @file-storage/gcs

If there is no configuration, it will uploads to local disk. You can specific yours by using config method:

import Storage from '@file-storage/core';
import { DriverName } from '@file-storage/common';

Storage.config({
  diskConfigs: [
    {
      driver: DriverName.LOCAL,
      name: 'local',
      root: 'public',
    },
    {
      driver: DriverName.S3,
      name: 'mys3',
      bucketName: 'mybucket',
      isDefault: true, // Default disk that you can access directly via Storage facade.
      // Uncomment if you want specify credentials manually.
      // region: 'ap-southeast-1',
      // credentials: {
      //   accessKeyId: '123abc',
      //   secretAccessKey: '123abc',
      // },
    },
  ],
});

// Somewhere in your code...
// Get file from s3:
Storage.get('/path/to/s3-bucket/my-image.png');

Obtain disk instance:

If you want to interact with a specific disk instead of the default, use disk method to get that instance:

Storage.disk('local').get('/path/to/local/my-image.png');

Unique file name

Enable unique file name to prevent a file get replaced when uploading same file (or same name). The unique name generated by uuid to secure your file path.

Storage.config({
  ...
  uniqueFileName: true,
});

// The uploaded path could be like this: /path/to/e8a3e633-fc7f-4dde-b7f0-d2686bcd6836.jpeg

Create your custom driver

If bult-in drivers doesn't match your need, just defines a custom driver by extends Driver abstract class:

import Storage from '@file-storage/core';
import { Driver } from '@file-storage/common';

interface OneDriveConfig {
  name: string; // driver instance name is required.
  ...
}

class OneDrive extends Driver {
  static readonly driverName = 'one_drive';

  constructor(config: OneDriveConfig) {
    super(config);
    ...
  }

  // Define all Driver's methods here.
}

And provide it to Storage.customDrivers:

Storage.config<OneDriveConfig>({
  diskConfigs: [
    {
      driver: 'one_drive',
      name: 'myCustomDisk',
      isDefault: true,
      ...
    }
  ],
  customDrivers: [OneDrive],
});

Image manipulation

If you want to upload image and also creates many diferent sizes for web resonsive, install this package, it is acting as a plugin, will generates those image sizes automatically:

$ yarn add @file-storage/image-manipulation

HINT: Image manipulation only available on Storage facade, If you obtain a specific disk instance, set the second parameter to true to obtain a storage instance insteads:

Storage.disk('your-disk', true); // Storage instance.

TODO

• Create interface for all result (Need same result format for all drivers).
• Refactor customDrivers option: provides disk defination is enough.
• Implement GCS disk.
• Put file from a local path.
• API section: detailed of each driver.
• Remove customDrivers option, pass custom driver class directly to diskConfigs.driver.
• Unique file name.
