TL-B Runtime

Quick Start

npm install @ton-community/tlb-runtime

Usage

Simple

import { parseTLB } from '@ton-community/tlb-runtime';

interface Data {
  kind: 'Foo';
  x: number;
}

// language=tlb
const runtime = parseTLB<Data>('_ x:# = Foo;')

const pack = runtime.serialize({
  kind: 'Foo',
  x: 73,
})
if (pack.success) {
  console.log({ pack: pack.value.endCell().toBoc().toString('base64')});
} else {
  console.error(pack.error.message);
}
// { pack: 'te6cckEBAQEABgAACAAAAEmTxmY2' }

const unpack = runtime.deserialize('te6cckEBAQEABgAACAAAACoFpvBE')
if (unpack.success) {
  console.log({ unpack: unpack.value});
} else {
  console.error(unpack.error.message);
}
// { unpack: { kind: 'Foo', x: 42 } }
