Your action template should have three variables in the top level scope:

1. FILE_EXTENSION: Extension of the file of your language.

2. routeTemplate: This is a function that takes in two arguments: 1) mutationSdl and typesSdl. You can parse this SDL into a document using the parse function from graphql. Based on these two documents, you should generate code for a route that will be appended to the route file specified in the config.yaml of your project.

3. handlerTemplate: This is a function that takes in two arguments: 1) mutationSdl and typesSdl. You can parse this SDL into a document using the parse function from graphql. Based on these two documents you should generate code for a function that accepts action payload, does some logic and returns a response. This function will be created in a file and be put up as `.<FILE_EXTENSION>.
