To check whether your Node.js and TypeScript versions work with Angular, find your project’s exact Angular major and minor release, then match it to the corresponding row in Angular’s official version compatibility table. The accepted ranges can change between minor releases in the same major version, so a neighboring row is not a safe substitute.
Check the exact Angular release line first
Angular’s compatibility table lists required Node.js, TypeScript, and RxJS versions by Angular release line. Find the version your project actually uses and compare each dependency against that row. For a quick check, inspect the project’s package.json and lockfile; the installed Angular packages may also be reported by ng version.
Here are examples from the live table retrieved on October 5, 2026. They illustrate why minor versions matter; they are not a recommendation to upgrade to a particular release. Confirm the current ranges on Angular’s compatibility page before changing dependencies.
| Angular release line | Node.js | TypeScript | RxJS |
|---|---|---|---|
| 22.0.x | ^22.22.3, ^24.15.0, or ^26.0.0 |
>=6.0.0 <6.1.0 |
^6.5.3 or ^7.4.0 |
| 21.0.x–21.2.x | ^20.19.0, ^22.12.0, or ^24.0.0 |
>=5.9.0 <6.0.0 |
^6.5.3 or ^7.4.0 |
| 20.2.x–20.3.x | ^20.19.0, ^22.12.0, or ^24.0.0 |
>=5.8.0 <6.0.0 |
^6.5.3 or ^7.4.0 |
| 20.0.x–20.1.x | ^20.19.0, ^22.12.0, or ^24.0.0 |
>=5.8.0 <5.9.0 |
^6.5.3 or ^7.4.0 |
For example, TypeScript 5.9 falls within the listed range for Angular 20.2.x–20.3.x but not for 20.0.x–20.1.x. A range match is not a guarantee that every combination has been tested in your application; check the precise Angular row and relevant package peer dependencies.

Read the version ranges correctly
Angular uses standard package-version range notation. A caret range such as ^22.12.0 allows compatible releases within that major version, starting at the stated minimum; it does not mean that only that exact version is accepted. An interval such as >=5.8.0 <5.9.0 includes versions from 5.8.0 up to, but not including, 5.9.0.
Use the range as Angular publishes it rather than assuming that the latest Node.js or TypeScript release will always work. If a tool or package manager reports a mismatch, check both the installed versions and the exact Angular line before changing anything.
Compatibility does not mean the Angular release is supported
The compatibility table includes historical rows as well as currently supported lines. A listed Node.js or TypeScript range tells you what Angular version requires; it does not promise ongoing support, security fixes, or future guarantees for an older Angular release. The table retrieved for this article marks Angular 20, 21, and 22 in its active-support section and identifies earlier rows as historical and unsupported. Since support status changes, check the live table rather than treating this snapshot as permanent.
Angular describes a typical major-version support period of 18 months: six months of active support followed by 12 months of long-term support. That is a general policy, not a current status guarantee for any particular release.
Plan upgrades to a supported destination, one major at a time
Angular’s upgrade guidance recommends moving to a supported destination and upgrading one major version at a time. If your application is several majors behind, perform the intervening major updates sequentially; Angular’s ng update command can apply migration transformations along the way. Major releases can require code changes, tests, or new APIs, while minor releases are intended to be backward-compatible and patch releases are generally lower-risk bug fixes.
Before choosing a target, compare the compatibility ranges with the Node.js versions available in development and deployment, your exact TypeScript version, RxJS, third-party package requirements, and browser needs. Angular’s guidance is documented in its update guide and release policy.

Check dependent libraries for version skew
Angular recommends that an application use the same or a newer Angular version than the Angular version used to build its dependent libraries. For npm libraries, Angular recommends Partial-Ivy, a portable format intended for applications from Angular v12 onward. Full-Ivy contains private Ivy instructions that are not guaranteed to remain compatible across Angular versions; a Full-Ivy library and its application must use exactly the same Angular version.
Partial compilation is intended as a stable intermediate format for independently published libraries. Full compilation is the default and is appropriate for most applications. See Angular’s library guidance and compiler documentation.

Browser support and polyfills are separate from Node.js compatibility
Passing the Node.js, TypeScript, and RxJS checks does not establish that an application supports a particular browser or has every required Web API. Angular 20 and later use the “widely available” Baseline, selecting a date near each major release. Angular describes this as browsers released within 30 months of that date in the core Chrome, Edge, Firefox, and Safari set, with a target of about 95% of web users. That percentage is Angular’s stated target, not a guarantee for an individual application.
Angular CLI uses Browserslist to align builds with supported browsers and can transform some JavaScript and CSS features, but it does not automatically add polyfills for missing Web APIs. If your application must support additional browsers or APIs, assess and configure polyfills separately; polyfills do not make an old, slow browser fast. See the Angular compatibility and browser guidance and CLI browser compatibility documentation.
