Debug Angular application in VSCode and Chromium

If you want debug Angular application in VSCode and Chromium in Linux that you should’t install extensions for that! You need add only one file launch.json in your project with this configuration:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch Chrome",
      "request": "launch",
      "type": "chrome",
      "url": "http://localhost:4200/#",
      "webRoot": "${workspaceFolder}",
      "runtimeExecutable": "/usr/bin/chromium",
      "runtimeArgs": [
        "http://localhost:4200",
        "--new-window",
        "-user-data-dir=${workspaceFolder}/DevProfile",
        "--remote-debugging-port=9222",
        "--disable-background-networking"
      ]
    }
  ]
}

Important notes

  1. check path to chromium binary file, for me it’s «/usr/bin/chromium».
  2. maybe you don’t need create user-data-dir for debug action.
  3. if you see error «unverified breakpoint» in VSCode that meen you need check path url and webRoot fields in your launch.json.

Bash scripts with NodeJS

Use Google’s package ZX for bash scripts on NodeJS: github and npm package.

Example:

#!/usr/bin/env zx

await $`cat package.json | grep name`

let branch = await $`git branch --show-current`
await $`dep deploy --branch=${branch}`

await Promise.all([
  $`sleep 1; echo 1`,
  $`sleep 2; echo 2`,
  $`sleep 3; echo 3`,
])

let name = 'foo bar'
await $`mkdir /tmp/${name}`

ImageMagick useful examples

Bash script with ImageMagick that resize and change qulity a lof of images

for img in ./*
do
	filename=$(basename "$img")
	filename="${filename%.*}"
	
	convert "$img" -auto-orient -resize 1000x -quality 85% "photos/$filename.jpg"
done;
