JavaScript browser bundles for the Postcode Lookup library

This package exports polyfilled, minified copies of postcode-lookup in various formats available on npm and various JavaScript cdns. It can be readily dropped in on a page without transpilation of postcode-lookup.

If you intend to incorporate the browser client in your own bundle, please use postcode-lookup as your package.json dependency.

Download

Download Latest Bundle

• postcode-lookup.js

Serving your own versioned copy is recommended. If a JavaScript CDN is used (e.g. jsDelivr, cdnjs), be sure to pin the version.

Use postcode-lookup.esm.js if you need a ES Module compatible build.

⚠️ Pinning Versions

It is important you pin your bundle version in production. Pulling directly from latest will cause your integration to fail at some point in the future.

For instance, follow the instructions on jsdelivr.com/postcode-lookup-bundled to pin a specific version in production. E.g.

<script
  src="https://cdn.jsdelivr.net/npm/@ideal-postcodes/postcode-lookup-bundled@2.0.0/dist/postcode-lookup.js">
</script>
