errgo-ts/dist/try-catch.js

A lightweight error handling library inspired by Go and Rust.

import { coerceError } from "./coerce-error.js";
export function tryCatch(action) {
    try {
        const result = action();
        if (result instanceof Promise) {
            return result.then((v) => ({
                val: v,
            }), (e) => ({
                err: coerceError(e),
            }));
        }
        else {
            return { val: result };
        }
    }
    catch (e) {
        return { err: coerceError(e) };
    }
}
