#gmlewis/spin-moonbit-sdk

This is an experimental Spin SDK for the MoonBit programming language. Please expect breaking changes while still experimenting with the API.

This is based on this blog post: https://www.moonbitlang.com/blog/component-model and this GitHub example: https://github.com/moonbitlang/moonbit-docs/tree/464356567270284446244cccecd101c04e9806f8/examples/wasi-http

#Templates

If you wish to install MoonBit templates for the Spin CLI tool (v3), you can run:

spin templates install --git https://github.com/gmlewis/spin-moonbit-sdk

The templates are located in the templates folder.

#Build (SDK Development)

Before building, you must have already installed the MoonBit programming language and the Spin CLI tool. You also need version v1.236.0 or later of wasm-tools.

To install MoonBit, follow the instructions here (it is super-easy with VSCode): https://www.moonbitlang.com/download/

If you already have the Rust programming language installed, you can install wasm-tools by typing:

cargo install --locked wasm-tools

Then, to build this SDK, clone the repo, and type:

moon update && moon install
moon build

#Examples

Examples can be found at: https://github.com/gmlewis/spin-moonbit-sdk-examples

To run an example, type:

$ cd examples/hello-world
$ spin up --build

then from another terminal, hit the endpoint with curl:

$ curl -i localhost:3000/hello
HTTP/1.1 200 OK
content-type: text/plain
transfer-encoding: chunked

Hello, World!

Each example contains a README. Please refer to the README for additional commands and setup instructions. It might also be required to issue an update command: moon update to retrieve the latest dependencies.
