Without a deterministic build I don't know what I check in actually works across environment, or if the deployment artifact works.

Actually that's mostly a given in JS land.

Many bright minds worked hard for it to be this level of idiot-proof.

I recently discovered that in node 10.10 (IIRC), you need oracledb < 4.0.0 whereas on other versions of node like node 10.16, you can use oracledb 4.0.1 (again, IIRC). I discovered this via the message when it blew up on application start, since it's not encoded in the package versions.

I may be a better idiot.

Oh, that.

Weird that it didn't complain during building or installation.

Anyway I had one project where I couldn't use `async` `await`, because apparently this feature requires Babel 7, which in turn requires a version of node fresh enough to support generators.

This tends to happen, but it's rare to discover such an issue only after starting the application.
