TypeScript Module System Demo

TypeScript: 5.0.0-dev.20230103

Legends

• 🟢: both compile and runtime are working correctly
• 🟡: for compile, it means there is an error, but can be suppressed (e.g. with skipLibCheck)
  for runtime, it means the compile fails, but runtime is working
• 🔴: compile and/or runtime fails
• ❌: compile success, but runtime fails. Potentially a TypeScript bug.
• ➖: invalid usage in this test configuration

Import Syntax:

• default as: import { default as m } from 'm'
• default: import m from 'm'
• * as: import * as m from 'm'
• named: import { something } from 'm'
