server restart when webpack throws warning [HMR] Cannot find update.

[veeramarni]

When we externalize the node_modules, webpack hot loader on the server side ignores any (lerna) packages that compiled recently by throwing the warning. Instead, we want the server to restart when we see this warning. In the earlier version, like 0.4.18 I noticed the server restart but in the latest version, I don't see this happening.

[HMR] Cannot find update.

I'm using this workaround, to check the status idle (noticed the status as idle when it throws the warning), if idle I'm exiting the process so it restarts.

if (module.hot) {
    module.hot.status(event => {
        logger.trace(event);
        if (event === 'abort' || event === 'fail') {
            logger.error('HMR error status: ' + event);
            // Signal webpack.run.js to do full-reload of the back-end
            process.exit(250);
        }
        if (event === 'idle') {
            process.exit(250);
        }
    });

    module.hot.accept();
}

Do you have any better suggestion?

@veeramarni Well, you can try to search through the guts of webpack to find a better solution, but your solution looks good enough to me

closing it as the workaround suffice.
