Using

look at index.test.ts for some useful helper functions for working with the package that you may want to use in your code.

svm_codev.wasm is not included in the package as different javascript apps will want to load it in different ways. e.g. load from app resources in a node.js or electron app. Load using a resources' loader in a web-app.

Electron / Node.js App

Add svm_codec.wasm to be used by the lib to your app's resources.

import fs from 'fs';
import Path from 'path';

import * as SvmCodec from '@spacemesh/svm-codec';

const path = Path.resolve(__dirname, 'svm_codec.wasm');
const code = fs.readFileSync(path);

await SvmCodec.init(code);

// call svmCodec functions...
