Graphql Mesh - Custom Transform

[Ramakant2021]

Hi

Can you please put a example of how can we develop custom transform in Graphql mesh.

I figured out how to do this by tracing it in the source code...it's pretty simple, I guess it just hasn't been documented yet.

The easiest way is to just create a local folder at the root of your project (same level as package.json) and give it the same name as your transform. So if you want to create a transform named foo, just create ./foo/index.ts and make the default export a class that implements the MeshTransform interface (see existing transforms for examples).

If you want to publish your transform as its own package (or as a package in a monorepo), you can use any of the following names for it (using foo as an example):

  '@graphql-mesh/foo',
  '@graphql-mesh/foo-transform',
  '@graphql-mesh/transform-foo',
  'foo',
  'foo-transform',
  'transform-foo',
  'foo',

(Note: I don't know if all of these are officially supported, those are just the possibilities I found in the source code.)
