Heroku buildpack: curl with HTTP/2 support
A Heroku buildpack that replaces the system curl with a custom version supporting HTTP/2 via nghttp2.
Overview
This Heroku buildpack shadows the system-provided curl executable and libcurl with a custom-built version that adds HTTP/2 support through nghttp2. It is designed to be used as an additional layer before the primary language buildpack, enabling HTTP/2 capabilities for applications deployed on Heroku.
Key Features
- HTTP/2 Support — Provides HTTP/2 functionality via nghttp2, which is not available in the default Heroku curl.
- Buildpack Integration — Works as a supplementary buildpack that can be added alongside language-specific buildpacks.
- System Shadowing — Replaces the system curl and libcurl with the custom version without requiring standalone usage.
Philosophy
The buildpack is designed to extend Heroku's capabilities by seamlessly adding modern HTTP/2 support to curl, ensuring compatibility and performance improvements for applications that rely on HTTP/2 features.
