Run sam local start-api watching for changes in TypeScript source files

sam build && concurrently "nodemon --on-change-only --ext ts --exec sam build" "sam local start-api"

Requires npm i -g nodemon concurrently

It runs nodemon and sam local start-api in the background simultaneously. The trick is to have the build available before creating docker image, so it's done beforehand and nodemon does it only after changes (using --on-change-only flag).

Fast lint with autofixer

for pre-commit hook

In order to run linter in a pre-commit hook you can check changed files only for performance reasons.

package.json:

{
  "scripts": [
    "fastlint": "git diff --cached --name-only | grep .ts$ |  xargs -L1 \"./node_modules/.bin/tslint\" --fix"
 ],
