ngtcp2 and nghttp3
The ngtcp2 and nghttp3 dependencies provide the core functionality for QUIC and HTTP/3.
The sources are pulled from:
- ngtcp2: https://github.com/ngtcp2/ngtcp2
- nghttp3: https://github.com/ngtcp2/nghttp3
In both the ngtcp2 and nghttp3 git repos, the active development occurs
in the default branch (currently named main in each). Tagged versions do not
always point to the default branch.
We only use a subset of the sources for each.
Updating
The nghttp3 library depends on ngtcp2. Both should always be updated
together. From ngtcp2 we only want the contents of the lib and crypto
directories; from nghttp3 we only want the contents of the lib directory.
After updating either dependency, check if any source files or include
directories have been added or removed and update ngtcp2.gyp accordingly.
Updating ngtcp2
The tools/dep_updaters/update-ngtcp2.sh script automates the update of the
ngtcp2 source files.
Check that Node.js still builds and tests.
- Add ngtcp2:
$ git add deps/ngtcp2 - Commit the changes:
git commit. - Add a message like:
deps: update ngtcp2 to <version> Updated as described in doc/contributing/maintaining-ngtcp2.md.
Updating nghttp3
The tools/dep_updaters/update-nghttp3.sh script automates the update of the
nghttp3 source files.
Check that Node.js still builds and tests.
- Add nghttp3:
$ git add deps/ngtcp2 - Commit the changes:
git commit. - Add a message like:
deps: update nghttp3 to <version> Updated as described in doc/contributing/maintaining-ngtcp2.md.
