Keytar VS Code Extensions

npm install & npm start here or in electron.

This repository demonstrates a weird Keytar issue where when loaded dynamically using require from a node file, the library seemingly works (doesn't work, but doesn't throw an error either) and just before the process exits, it throws a junk exception:

# Fatal error in , line 0
# Check failed: receiver->IsJSFunction().
# FailureMessage Object: 000000B5BCDBDA20npm
# errno 3221225477

(In the electron repro the file name and line number is okay.)

The require seems to go through and resolves to the correct instance whose methods setPassword and findPassword both work as well, but then it crashes.

Funnily enough, when the last line of code is process.exit(0), it doesn't crash, even though there is no more code in either case. It's almost as if some sort of a destructor ran and in it the library threw the exception and process.exit prevented it from running thus leaking the library.

Of course this workaround doesn't help because the findPassword method still returns undefined.

I have filed a Keytar GitHub issue for this problem linking to this repro.

---

In microsoft/vscode#68738 it is shown how to use VS Code's bundled Keytar which might be an acceptable workaround / fallback mechanism.

This is prototyped in code - instead of scaffolding and committing the extensions, I do that on the fly using Yeoman so that it's code doesn't go out of date or interfere with understanding of the core of the workaround.

async function activate() {
	const keytar = require('keytar');
	await keytar.setPassword('TEST', 'Tom', 'PASSW0RD');
	const password = await keytar.getPassword('TEST', 'Tom');
}

To-Do

Finalize patching the generated extension's package.json

To have a * for an activation event and for its activate to be the above.
