TypeScript HTTP Hello World

This repository contains a Hello World HTTP WebAssembly component example, written in TypeScript.

This component:

• Uses TypeScript for its implementation
• Uses the wasi:http standard WIT definitions
• Returns "hello from TypeScript" to all HTTP requests

Dependencies

![WARN] When building this project, ensure you are using a stable NodeJS release.

Use of node version management tools (ex. nvm or more newer NVM compatible tools like fnm) are recommended -- a .nvmrc file is included for easy use.

Building this project relies on the following software:

Name	Description
wash	Wasm Shell helps build, develop, and publish WebAssembly components
npm	Node Package Manager (NPM) manages packages for the NodeJS ecosystem
node	[NodeJS runtime][nodejs] (see .nvmrc for version)

Quickstart

To get started developing this project quickly, clone the repo and run wash dev in this directory:

wash dev

wash dev does many things for you:

• Builds this project (including necessary npm script targets)
• Runs the component locally, exposing the application at localhost:8000
• Watches your code for changes and re-deploys when necessary.

Send a request to the running component

Once wash dev is serving your component, send a request to the running component:

curl localhost:8000
