# apollo-reporting-protobuf > **Note:** The Apollo usage reporting API is subject to change. We strongly encourage developers to contact Apollo support at `support@apollographql.com` to discuss their use case prior to building their own reporting agent using this module. This module provides JavaScript/TypeScript [Protocol buffer](https://developers.google.com/protocol-buffers/) definitions for the Apollo usage reporting API. These definitions are generated for consumption from the `reports.proto` file which is defined internally within Apollo. ## Development > **Note:** Due to a dependency on Unix tools (e.g. `bash`, `grep`, etc.), the development of this module requires a Unix system. There is no reason why this can't be avoided, the time just hasn't been taken to make those changes. We'd happily accept a PR which makes the appropriate changes! Currently, this package generates a majority of its code with `@apollo/protobufjs` (a fork of [`protobufjs`](https://www.npmjs.com/package/protobufjs) that we maintain specifically for this package) based on the `reports.proto` file. The output is generated with the `generate` npm script. The root of the repository provides some `devDependencies` necessary to build these definitions and the `prepare` npm script is invoked programmatically via the monorepo tooling (e.g. Lerna) thanks to *this* module's `postinstall` script. Therefore, when making changes to this module, run scripts via `npx lerna run SCRIPTNAME` in the **root** of this monorepo in order to update the definitions in *this* module. To update `reports.proto` to the current version recognized by the Studio usage reporting ingress, run `lerna run update-proto`. To then regenerate the JS and TS files, run `npx lerna run generate`. We check in the generated code and only regenerate it manually, partially to make builds faster (no need to run pbjs on every `npm install`) and partially so that we don't have to make sure that `pbjs` runs on every Node version that we support. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.mediamagic.dev/product-docs/services/graphql-gateway/node_modules/apollo-reporting-protobuf.md?ask= ``` The question should be specific, self-contained, and written in natural language.
