ZettelKasten part 8

This is a followup to a previous article, ZettelKasten Part 7

Source maps

Source Maps what are they good for? Finding out where the heck problems are. Since I'm writing in typescript I'm seeing all sorts of fun issues where I see an error and it tells me where it is. In the compiled JS. Which isn't useful since that's not the files I'm editing.

In tsconfig.json:

{
  "compilerOptions": {
    "outDir": "dist",
    "esModuleInterop": true,
    "sourceMap": true
  },
  "exclude": ["node_modules", "tst"]
}

And I try it out by throwing an exception in the middle of my list API.

And it still sucks:

Error: Bad thing happened
    at /home/user/projects/ZettelKasten/dist/index.js:96:23
    at step (/home/user/projects/ZettelKasten/dist/index.js:33:23)
    at Object.next (/home/user/projects/ZettelKasten/dist/index.js:14:53)
    at fulfilled (/home/user/projects/ZettelKasten/dist/index.js:5:58)
    at processTicksAndRejections (node:internal/process/task_queues:94:5)

Hmmmm....

Stack Overflow says "do a bunch more stuff"

So:

yarn add source-map-support

And then in my package.json:

    "server": "npx tsc && node -r source-map-support/register dist/index.js",
    "migrate": "npx tsc && yarn copyFiles && node -r source-map-support/register dist/migration.js",

Error: Bad thing happened
    at /home/user/projects/ZettelKasten/src/index.ts:50:11

Perfect.

Moving on.
