Initializing​

OrionJS provides file upload and management through the file-manager package.

npm install @orion-js/file-manager

Configuration​

The configuration of file-manager is done by setting the following environment variables:

  • AWS_S3_ACCESS_KEY_ID: A valid AWS Access Key used along with the AWS_S3_SECRET_ACCESS_KEY to cryptographically sign programmatic AWS requests.
  • AWS_S3_SECRET_ACCESS_KEY: A valid AWS Secret Access Key corresponding to the previous key.
  • AWS_S3_BUCKETNAME: The name of the bucket where uploaded files will be storaged into.
  • AWS_S3_REGION: The region where the bucket resides.

To enable file management you must pass the options when initializing the File-Manager resolvers.

import {resolvers, setupFileManager} from '@orion-js/file-manager'

const options = {
  accessKeyId: <AWS_S3_ACCESS_KEY_ID>,
  secretAccessKey: <AWS_S3_SECRET_ACCESS_KEY>
  bucket: <AWS_S3_BUCKETNAME>,
  region: <AWS_S3_REGION>,
  basePath: 'basePath',
  canUpload: function(params, viewer) {
    return true
  }
}

setupFileManager(options)

export default {
  ...resolvers
}

inside the options object sended to setupFileManager must be entered the credentials of the S3 storage of AWS that will be used. Particularly, basePath receives a string with the route folder used to storage a particular oploaded file.

Uploading a File​

Setting a File type in schema​

When creating a new Schema, a File type can be set along the basic type properties already defined.

import {File} from '@orion-js/file-manager'

export default {
  title: {
    type: String
  },
  description: {
    type: String
  },
  cover: {
    type: File
  }
}

Uploading file​

File has its own internal schema (see File). When uploading a document with a File type field, make sure that the JSON uploaded inside the document fits the File schema so it passes it's respective schema validations.

Getting file data​

As mentioned before, File is a Model by itself with its own schema, which implies that accessing its information has its own set of rules. The File Model possesses the following ready-to-access properties:

  • key : The name of the file in the S3 storage, with its own concatenated hash.
  • bucket : The name of the bucket used to upload an keep the uploaded files in the S3 storage.
  • name : The original name of the file.
  • type : The type of the file. Currently, it manages png and jpg for images, and pdf.
  • size : The amount of bytes of the file.

Besides, the URL of the file saved in the S3 storage can be obtained through the url() model resolver:

const album = await Albums.findOne(albumId)
// album = {title, description, cover}
return await album.cover.url()
