How to develop a code generator?

[olmohake]

We are currently trying to setup a custom code generator, but struggling to point hasura to our generator file.
I was expecting to be able to do this via HASURA_GRAPHQL_ACTION_CODEGEN_URI or actions.codegen.uri however this setting seems to have no effect, as hasura keeps telling me the following:

could not find codegen config. For adding codegen config, run:  hasura actions use-codegen 

Running hasura actions use-codegen only enables me to setup an existing code generator, which is not what i am looking for. Is there anyway to point hasura to a local code generator file for development?

Hello @OLM0

From what I am reading, you need to build a custom codegen which isn't in lists provided by hasura CLI. Therefore, you'll need to contribute to codegen assets to build one. Currently, there isn't a way to point to local codegen.

Here's the link to contribution guide - https://github.com/hasura/codegen-assets/blob/master/builder-kit/README.md

Once you've built a custom codegen, file a PR against this repository - https://github.com/hasura/codegen-assets. We'll take it forward then.

Does that help your question ?
