Funny Developing Mistakes I Wasted Hours on

Using Routing Module Instead Of Module

Because there were no erros in the console and whatever in the component file doesn't render.

const routes: Routes = [
  {
    path: 'items',
    loadChildren: () => import('./comps/CompsRoutingModule.module').then(m => m.CompsRoutingModule)
  }
// That should have been just module.
];

Same Variable Names Different Files

Sometimes we may introduce the same function or variable name in a different context. This can cause VS Code to mess up the imports we were looking for, especially if we didn't know that the name had already been used.

yarn dev vs yarn start

yarn start doesn't refresh changes on file save. I sometimes accidently select start.

Using Wrong Environments in Postman

I just hit some post request to production without realizing for 10 mins.
