# python-wasm-component
Build a wasm component from a python http app
1. Create a wit directory with a world that conforms to an http trigger which essentially means you need a world that exports
a wasi http incoming handler type
2. Generate bindings using [componentize-py](https://github.com/bytecodealliance/componentize-py). By default, bindings will be created in a directory with the same name as the world you are targeting (replacing hyphens with underscores).
```bash
componentize-py -d wit -w http-app bindings .
```
3. Create the http handler in app.py using imports from the bindings that were generated.
4. Run `spin up --build` to build and run your component. Under the hood `spin build` is running `componentize-py -d wit -w http-app componentize app -o app.wasm` which builds you WASM component and outputs it as `app.wasm`.
5. Test using curl
```console
$ curl -i localhost:3000
HTTP/1.1 200 OK
hello: WORLD
content-length: 0
date: Thu, 02 Nov 2023 22:25:33 GMT
```
Enjoy!
