Module Error Handling

Express doesn’t handle async/await errors properly with an errorhandler - we need to use express-async-handler:

router.get(
    "/quote",
    asyncHandler(async (req, res) => {
        res.json({
            status: "success",
            data: await bugQuote(),
        });
    })
);

Any error thrown inside the async function will automatically be passed to Express’s error handler.

Throwing errors in services

Inside module services, log the error and then throw a new one. This ensures it’s visible in logs and propagated to the router:

    try {
        await buildModule(moduleName);
    } catch (error) {
        logger.warn(`module-build: ${error.stack || error || error.message}`);
        throw new Error(`Failed to build module ${moduleName}`);
    }

If a step fails and you want to stop execution immediately, simply throw an error:

throw new Error(`Failed to write dockerfile to '${modulePath}'`);
