Compile JavaScript to WASM.
npm i ishvara -g
Let's suppose we have absolutely valid JavaScript file with types, which we can run with node v24.
import {create} from '#ishvara';
export const stack = [];
export const imports = [
['console', 'log', function log() {
return i32;
}],
];
const {
i32,
local,
call,
} = create({
stack,
imports,
});
export function x(a: i32, b: i32): i32 {
i32.add(local.get(a), local.get(b));
call('log');
}Compiled with ishvara 1.wast.ts to 1.wast:
(module
(import "console" "log" (func $log (param $message i32) (result i32)))
(func $x (export "x") (param $a i32) (param $b i32) (result i32)
(i32.add (local.get $a) (local.get $b))
(call $log)
)
)With:
import {compile} from 'ishvara';
const wast = compile(wastts);
const binary = await translate(wast);
const {x} = run(binary, {
console: {
log: (a) => {
console.log(a);
return a;
},
},
});
x(1, 2);
// outputs
