kwruntime/core (2.x)

Major update for this project. The entire process of importing URLs, files, and other languages has been redesigned.

Features of kwruntime/core

• Allows importing URLs (in the style of Deno)
• Allows importing npm packages directly at runtime, even for ESM packages
• Built-in support for TypeScript and Civet

Getting started

For installation instructions, click here: INSTALL

kwruntime /path/to/file.civet

Within node.js

const {kwruntime} = require("@kwruntime/core")

main()
async function main(){
    const axios = await kwruntime.import("npm:axios@0.27.2")
    const response = await axios("https://ipinfo.io")
    console.info("Response:", response.data)
}

or setting the execution to a file (similar result to how it would be executed in the terminal):

const {kwruntime} = require("@kwruntime/core")
// execute the file server.civet
kwruntime.main([process.argv[1], __dirname + "/server.civet"])

Typescript and civet support

interface Person {
  name: string;
  age: number;
}

function greet(person: Person): string {
  return "Hello, " + person.name + "!";
}

const alice: Person = {
  name: "Alice",
  age: 36
};

console.log(greet(alice));

You can also write in Civet:

interface Person
    name: string
    age: number

function greet(person: Person): string
    return "Hello, " + person.name + "!"

alice: Person := 
    name: "Alice"
    age: 36
    
console.log greet alice

Output:

kwruntime test.civet
Hello, Alice!

import from NPM packages, no need to install

Example: server.civet using express

express from "npm:express@4.18.2"

app := express()
app.get "/", (req, res): void =>
    res.send "Welcome to the kwruntime!"
app.listen 8000
console.info "Server active"

And test:

curl http://127.0.0.1:8080
Welcome to the kwruntime!

import from URL

express from "https://esm.sh/express@4.21.2"

app := express()
app.get "/", (req, res): void =>
    res.send "Welcome to the kwruntime!"
app.listen 8000
console.info "Server active"

WARNING: Importing from esm.sh is a bit slow at the moment. It is recommended to import using npm as in the previous example.
