AWS S3 File Upload Configuration

In order to use this component, the following configuration needs to be added to a PubSweet application inside a section named pubsweet-component-aws-s3:

• secretAccessKey: the AWS_S3_SECRET_KEY value from the app's .env file
• accessKeyId: the AWS_S3_ACCESS_KEY value from the app's .env file
• region: the AWS_S3_REGION value from the app's .env file
• bucket: the AWS_S3_BUCKET value from the app's .env file

For example:

"pubsweet-component-aws-s3": {
    "secretAccessKey": "process.env.AWS_S3_SECRET_KEY",
    "accessKeyId": "process.env.AWS_S3_ACCESS_KEY",
    "region": "process.env.AWS_S3_REGION",
    "bucket": "process.env.AWS_S3_BUCKET",
    "validations": "path.resolve(__dirname, 'upload-validations.js')",
  },

The .env file should look like this:

AWS_S3_ACCESS_KEY = exampleKey
AWS_S3_SECRET_KEY = exampleKey/sads/21
AWS_S3_REGION = region-name
AWS_S3_BUCKET = bucket-name

Then, as soon as possible in your app you should add the dotenv package:

require('dotenv').config()
