Configuration

• provider defines the name of the provider
• providerOptions is passed down during the construction of the provider. (ex: new AWS.S3(config)). Complete list of options
• actionOptions is passed directly to the parameters to each method respectively. You can find the complete list of upload/ uploadStream options and delete options

See the documentation about using a provider for information on installing and using a provider. To understand how environment variables are used in Strapi, please refer to the documentation about environment variables.

Provider Configuration

./config/plugins.js or ./config/plugins.ts for TypeScript projects:

module.exports = ({ env }) => ({
  // ...
  upload: {
    config: {
      provider: "@bangprovn/provider-upload-aws-s3-cloudfront",
      providerOptions: {
        accessKeyId: env("AWS_ACCESS_KEY_ID"),
        secretAccessKey: env("AWS_ACCESS_SECRET"),
        region: env("AWS_REGION"),
        params: {
          Bucket: env("AWS_BUCKET"),
        },
        cdn: env("AWS_CLOUDFRONT_CDN"),
      },
      actionOptions: {
        upload: {},
        uploadStream: {},
        delete: {},
      },
    },
  },
  // ...
});

Configuration for S3 compatible services

This plugin may work with S3 compatible services by using the endpoint option instead of region. Scaleway example: ./config/plugins.js

module.exports = ({ env }) => ({
  // ...
  upload: {
    config: {
      provider: "@bangprovn/provider-upload-aws-s3-cloudfront",
      providerOptions: {
        accessKeyId: env("SCALEWAY_ACCESS_KEY_ID"),
        secretAccessKey: env("SCALEWAY_ACCESS_SECRET"),
        endpoint: env("SCALEWAY_ENDPOINT"), // e.g. "s3.fr-par.scw.cloud"
        params: {
          Bucket: env("SCALEWAY_BUCKET"),
        },
        cdn: env("AWS_CLOUDFRONT_CDN"),
      },
    },
  },
  // ...
});

Security Middleware Configuration

Due to the default settings in the Strapi Security Middleware you will need to modify the contentSecurityPolicy settings to properly see thumbnail previews in the Media Library. You should replace strapi::security string with the object bellow instead as explained in the middleware configuration documentation.

./config/middlewares.js

module.exports = [
  // ...
  {
    name: "strapi::security",
    config: {
      contentSecurityPolicy: {
        useDefaults: true,
        directives: {
          "connect-src": ["'self'", "https:"],
          "img-src": [
            "'self'",
            "data:",
            "blob:",
            "dl.airtable.com",
            "yourBucketName.s3.yourRegion.amazonaws.com",
            // Your CDN url
          ],
          "media-src": [
            "'self'",
            "data:",
            "blob:",
            "dl.airtable.com",
            "yourBucketName.s3.yourRegion.amazonaws.com",
            // Your CDN url
          ],
          upgradeInsecureRequests: null,
        },
      },
    },
  },
  // ...
];

If you use dots in your bucket name, the url of the ressource is in directory style (s3.yourRegion.amazonaws.com/your.bucket.name/image.jpg) instead of yourBucketName.s3.yourRegion.amazonaws.com/image.jpg. Then only add s3.yourRegion.amazonaws.com to img-src and media-src directives.

Bucket CORS Configuration

If you are planning on uploading content like GIFs and videos to your S3 bucket, you will want to edit its CORS configuration so that thumbnails are properly shown in Strapi. To do so, open your Bucket on the AWS console and locate the Cross-origin resource sharing (CORS) field under the Permissions tab, then amend the policies by writing your own JSON configuration, or copying and pasting the following one:

[
  {
    "AllowedHeaders": ["*"],
    "AllowedMethods": ["GET"],
    "AllowedOrigins": ["YOUR STRAPI URL"],
    "ExposeHeaders": [],
    "MaxAgeSeconds": 3000
  }
]

Required AWS Policy Actions

These are the minimum amount of permissions needed for this provider to work.

"Action": [
  "s3:PutObject",
  "s3:GetObject",
  "s3:ListBucket",
  "s3:DeleteObject",
  "s3:PutObjectAcl"
],
