An HTTP microframework for the Grain programming language built on top of WAGI, a CGI v1.1 server implementation for WebAssembly. Like its namesake, Hopper allows you to dispense your Grain (to users across the internet, that is *wink*).
Hopper allows you to quickly structure an HTTP server/API for use by your web app or otherwise. It is intentionally minimal; rather than aiming to be a complete, fully-featured web application framework, it aims to provide a foundation flexible enough to be used as a base for a wide array of use cases, while being easy to extend in order to fit specific scenarios.
Key features:
- Simple paradigm for handling HTTP requests and responses
- Routing system with regex-based matching and route nesting to make organizing HTTP routes easy
- Composable middleware system to enable code reuse and extensibility
NOTE: Express caution if using Hopper in any serious application. Hopper is built on experimental technology and is currently in an early stage, having not been thoroughly vetted for robustness and/or security vulnerabilities. Furthermore, its API is likely to change in the future as new features get added to Grain and/or WAGI.
Usage guides as well as API docs can be found in the docs directory of this repo.
Here is a list of extensions adding functionality onto Hopper that may be useful to you:
- hopper-form, for handling HTML form bodies
- hopper-cors, for handling CORS requests
If you have created an extension to Hopper adding useful functionality, feel free to open a PR adding to this list.
If you find a bug or have a suggestion for improving Hopper, feel free to open a GitHub issue or fork the repo and open a PR!
Hopper was heavily inspired by other HTTP server libraries, most prominently Dream and Express. Hopper would also not be possible without all of the foundation it stands upon, including the Grain programming language and WAGI ❤️
