Default starter for JavaScript

A basic starter kit that demonstrates routing, simple synthetic responses and overriding caching rules.

Fastly Compute

Use this starter

Using the Fastly CLI, create a new project using this starter somewhere on your computer:

$ fastly compute init --from=

Or click the button below to create a GitHub repository, provision a Fastly service, and set up continuous deployment:

Deploy to Fastly


  • Allow only requests with particular HTTP methods
  • Match request URL path and methods for routing
  • Build synthetic responses at the edge

Understanding the code

This starter is intentionally lightweight, and requires no dependencies aside from the @fastly/js-compute npm package. It will help you understand the basics of processing requests at the edge using Fastly. This starter includes implementations of common patterns explained in our using Compute and VCL migration guides.

The starter doesn't require the use of any backends. Once deployed, you will have a Fastly service running on Compute that can generate synthetic responses at the edge.

The template uses webpack to bundle index.js and its imports into a single JS file, bin/index.js, which is then wrapped into a .wasm file, bin/index.wasm using the js-compute-runtime CLI tool bundled with the @fastly/js-compute npm package, and bundled into a .tar.gz file ready for deployment to Compute.
