gatsby-plugin-s3

![](https://img.shields.io/circleci/build/github/jariz/gatsby-plugin-s3?label=e2e

Enables you to deploy your gatsby site to a S3 bucket.
Requires very little configuration, while optimizing your site as much as possible.

Features:

  • 📦 Fully handles the deployment process for you, all you need to configure is your bucket name.
    • Automatically creates/updates bucket with optimal configuration applied.
    • Syncs gatsby files to the bucket & updates metadata.
  • ⏭ Redirects.
  • 💾 Optimizes caching for you.
  • ☁️ Optional serverless framework support if you want to take things a step further.
  • ✏️ Add your own params to uploaded S3 objects (if you wish).

Usage

Install the plugin:

npm i gatsby-plugin-s3

Add it to your gatsby-config.js & configure the bucket name (required)

plugins: [
  {
      resolve: `gatsby-plugin-s3`,
      options: {
          bucketName: 'my-website-bucket'
      },
  },
]

There are more fields that can be configured, see below.

Add a deployment script to your package.json

"scripts": {
    ...
    "deploy": "gatsby-plugin-s3 deploy"
}

Optionally you can skip the confirmation prompt automatically by adding --yes like so:

    "deploy": "gatsby-plugin-s3 deploy --yes"

When gatsby-plugin-s3 detects a CI environment, it will automatically skip this prompt by default.

After configuring credentials (see below), you can now execute npm run build && npm run deploy to have your site be build and immediately deployed to S3.

Credentials

Globally

A couple of different methods of specifying credentials exist, the easiest one being using the AWS CLI:

# NOTE: ensure python is installed
pip install awscli
aws configure

Environment variables

If you don't want to have your credentials saved globally (i.e. you're dealing with multiple tokens on the same environment), they can be set as environment variables, for example:

AWS_ACCESS_KEY_ID=xxxx AWS_SECRET_ACCESS_KEY=xxxx npm run deploy

Additionally, these can be set in a local .env file too, but this requires a bit more setup work. See the recipe here.

Configuration

Recipes

Several recipes are available:

Adding environment specific settings

Learn how to retrieve AWS credentials from a .env file. Additionally setup a different bucket name depending on your environment.

Using a different content type for files

Learn how to override the content type gatsby-plugin-s3 sets on your files.

Using CloudFront with gatsby-plugin-s3

CloudFront is a global CDN and can be used to make your blazing fast Gatsby site load even faster, particularly for first-time visitors. Additionally, CloudFront provides the easiest way to give your S3 bucket a custom domain name and HTTPS support.

Using serverless with gatsby-plugin-s3

Serverless can be used in combination with gatsby-plugin-s3, swapping the plugin's deployment step for sls deploy instead.
Serverless will give you the added advantage of being able to add multiple AWS services such as Lambda, CloudFront, and more all in the same repo, deployment step and CloudFormation stack while still being able to profit from all the optimisations gatsby-plugin-s3 does.

Using a proxy

Routing traffic from gatsby-plugin-s3 during the deployment through a http proxy can be done with a env var.

Configuring a custom endpoint

Using Yandex, DigitalOcean, or any other S3-compliant storage service together with gatsby-plugin-s3

Deploying your gatsby site under a prefix in your bucket

You can deploy your site to a prefix, leaving all other data in the bucket intact. gatsby-plugin-s3 respects the pathPrefix gatsby option with no additional setup needed for this plugin, so you can follow the guide in the gatsby docs.

AWS S3 Routing Rules Limit

AWS S3 has an undocumented limit on the number of Routing Rules that can be applied to a bucket. Unfortunately this limits the number of 302 (temporary) redirects you can create. For 301 (permanent) redirects, a way to get around the limit is setting the x-amz-website-redirect-location header on an empty object. To enable this behavior, set the generateRedirectObjectsForPermanentRedirects configuration option to true.
