Formatting TypeScript

#54820

• dprint - extremely fast, used by Deno itself.
• Can easily support format-on-save in the checker instantaneously.
• Looking at formatting DefinitelyTyped with a different config.
• What's the workflow?
  • Recommend installing dprint formatting extension.
  • npm run format
  • CI checks ensure that.
• Prettier is a lot more prescriptive. dprint is closer to gofmt or to some extent the TypeScript formatter, keeps general intent.
  • Our lines length is set to 1000 (!)
  • Some prescritive views on when to swap to multiline.
  • Still knobs if you need.
• Some stuff that's not yet supported:
  • Single imports on the same line.
  • Space-aligned comments.
