Edge runtime

This directory contains the logic required to create Netlify Edge Functions to support a Next.js site.

It stands out from the rest of the project because it contains files that run in Deno, not Node.js. Therefore any files within edge-runtime/ should not be imported from anywhere outside this directory.

There are a few sub-directories you should know about.

`lib/`

Files that are imported by the generated edge functions.

`shim/`

Files that are inlined in the generated edge functions. This means that you must not import these files from anywhere in the application, because they contain just fragments of a valid program.

`vendor/`

Third-party dependencies used in the generated edge functions and pulled in ahead of time to avoid a build time dependency on any package registry.

This directory is automatically managed by the build script and can be re-generated by running npm run build.

You should not commit this directory to version control.
