Bug: WASM library is crashing in Node.js #1062
Description
Describe the bug
The package wasm-themis can not be used with Node.js because it tries to call fetch() on a file path.
To Reproduce
Steps to reproduce the behavior:
- Install Node.js v22
- Run
npm i wasm-themis - Minimal example script
const themis = require('wasm-themis');
async function test() {
await themis.initialized;
console.log('Themis initialized');
const keyPair = new themis.KeyPair();
console.log('Generated key pair:', keyPair);
}
test();Exception:
TypeError: fetch failed

}
Expected behavior
A clear and concise description of what you expected to happen.
Environment (please complete the following information):
- OS: Windows 11
- Hardware: 64-bit
- Themis version: [email protected]
- Installation way: via package manager
Additional context
A temporary workaround I found is modifying the function instantiateAsync in the file libthemis.js by adding return instantiateArrayBuffer(receiveInstantiationResult); to the begging of the function.
