S3 invalidate CloudFront

Invalidate CloudFront caches for a bucket.

Motivation

After uploading to an S3 bucket I need to invalidate the CloudFront cache:

> aws s3 sync src/ s3://bucket-name
> aws cloudfront create-invalidation --distribution-id cloudfront-distribution-id --paths "/*"

The AWS cli only accepts distribution IDs which then have to be hardcoded. It would be much more ergonomic if I could lookup the matching distribution IDs based on the bucket name:

> s3-invalidate-cloudfront bucket-name

Deleted cloudfront-distribution-id at path /*

Benefits:

• Uses the bucket name which is recognisable and not allocated by AWS like the distribution ID
• Simplifies invalidating caches for a bucket that has multiple cloudfront consumers

I also want to programmatically invalidate caches:

import { lookup, invalidate } from "s3-invalidate-cloudfront";

lookup("bucket-name", "us-east-1").then((caches) => Promise.all(caches.map(invalidate)));

Installing

npm install s3-invalidate-cloudfront

To make the cli accessible install the package globally with the -g flag or invoke it with npx.

Usage

s3-invalidate-cloudfront bucket-name

CLI

s3-invalidate-cloudfront <name>

Invalidate CloudFront caches for a bucket.
