Vercel Dev Builder (vercel-dev-builder)

This is a "passthrough-Builder" for Vercel that is meant for use within the repo of your custom Vercel Builder. It makes developing Builders easier by being able to deploy any change to the Builder without needing to publish the package to the npm registry.

All the Builder functions are very simple passthrough functions that require() the code at the root of the repository and then execute the Builder's implementation.

When deploying to Vercel, it runs npm install and the "build" script specified in the package.json file to build the Builder if necessary. This is done for compatibility with Git deployments (where the source code is not built), allowing every commit to the Builder repo to be deployed to Vercel without needing to publish the changes to the npm registry.

For development with the vercel dev command, it is assumed that you have the npm dependencies installed and have built the Builder if necessary.

Usage

Specify vercel-dev-builder in your vercel.json file:

{
	"version": 2,
	"functions": {
		"api/**/*.abc": { "runtime": "[email protected]" }
	}
}

Note: Be sure to place the vercel.json file in the root directory of your project.

For some real-world usage examples, see vercel-deno or vercel-bash.
