# Maintaining nghttp2 in Node.js The low-level implementation of [HTTP2](https://nodejs.org/docs/latest/api/http2.html) is based on [nghttp2](https://nghttp2.org/). Updates are pulled into Node.js under [deps/nghttp2](https://github.com/nodejs/node/tree/HEAD/deps/nghttp2) as needed. The low-level implementation is made available in the Node.js API through JavaScript code in the [lib](https://github.com/nodejs/node/tree/HEAD/lib) directory and C++ code in the [src](https://github.com/nodejs/node/tree/HEAD/src) directory. ## Step 1: Updating nghttp2 The `tools/dep_updaters/update-nghttp2.sh` script automates the update of the postject source files. ## Step 2: Test the build ```console $ make test-http2 ``` ## Step 3: Commit new nghttp2 ```console $ git add -A deps/nghttp2 $ git commit -m "deps: upgrade nghttp2 to x.y.z" ``` ## Step 4: Update licenses ```console $ ./tools/license-builder.sh # The following commands are only necessary if there are changes $ git add . $ git commit -m "doc: update nghttp2 LICENSE using license-builder.sh" ```
