How do people deal with dependencies for processes?

[TylerBrock]

Lets say we have one Procfile entry (a) that depends on another (b) but (b) takes a long time to start. With node-foreman (a) sometimes fails because (b) isn't ready when (a) starts.

For example our web process (a) depends on the MongoDB process (b) being started.

The best thing I can think of (so far) is to add a wrapper shell script that starts (b) which sleeps for a bit before trying to start it, but this is pretty lame. What do other people do in this situation?

I would not start a database process with foreman, instead use the startup tools of your prefered Linux distribution.

It's also possibly a good idea to re-connect to a database in an error handler in your Node.js app if the connection is dropped.

Agree with @nilskassube on production usage, however in my development environment I am using await-url to wait for webpack-dev-server to perform the first build for hot module replacement before launching electron on the build. Works well!

We did what @nilskassube suggested and it was a good call. Now we've moved to docker-compose which handles everything for us.
