Worker Runtime

Findkit Workers is a custom V8 runtime which implements few browser APIs.

We use a recent version of V8 meaning most modern Javascript features are available but it should be noted that the runtime is not Node.js or a web browser. So there's no require(), import or any other Node.js APIs available. Also it does not execute the Javascript present on the web pages. Only the code you provide is executed.

Javascript API

In addition to standard Javascript APIs present in V8 the runtime has following browser APIs:

• Partial Fetch API
  • fetch(), Request, Response, Headers
  • Not all Fetch API features are supported but we are working on adding more
  • If you hit any limitations please contact us so we known what to prioritize, thanks!
• URL and URLSearchParams
• URLPattern
• btoa and atob
• AbortSignal and AbortController
• TextEncoder and TextDecoder
• structuredClone

Using npm modules

If you need to use a npm module you can use a bundler to include it within your code. Just point the workers = [] to the output bundle. We recommend esbuild for bundling. Use the ESM output format.
