Angular 17.3.x requirements
No longer supported: no fixes or security patches. Plan an upgrade.
| Needs | Supported range | Recommended |
|---|---|---|
| Node.js | ^18.13.0 || ^20.9.0 | Node 20 LTS (20.9.0+) |
| TypeScript | >=5.2.0 <5.5.0 | TypeScript 5.4 |
| RxJS | ^6.5.3 || ^7.4.0 | RxJS ^7.4.0 |
Every Node.js line that Angular 17.3.x supports has reached end of life (Node 20 ended 2026-04-30). Upgrading Angular is the only way back to a supported Node.js.
