@arrirpc/codegen-utils

This library contains a number of utilities that to assist in creating generators for Arri RPC. To See more complete usage example checkout one of the official arri client generators.

Creating a Generator Plugin

import { defineGeneratorPlugin } from "@arrirpc/codegen-utils";

// add any options needed for your plugin here
export interface MyPluginOptions {
    a: string;
    b: string;
}

export default defineGeneratorPlugin((options: MyPluginOptions) => {
    return {
        options,
        run: async (appDef, isDevServer) => {
            // generate something using the app definition and the specified options
        },
    };
});
