# Version compatibility
2+
3+
The following tables describe the versions of Node.js, TypeScript, and RxJS that each version of
4+
Angular requires.
5+
6+
## Actively supported versions
7+
8+
This table covers [Angular versions under active support](reference/releases#actively-supported-versions).

## Unsupported Angular versions
20+
21+
This table covers Angular versions that are no longer under long-term support (LTS). This
22+
information was correct when each version went out of LTS and is provided without any further
23+
guarantees. It is listed here for historical reference.

## Browser support
73+
74+
Angular uses the ["widely available" Baseline](https://web.dev/baseline) to define browser
75+
support. For each major version, Angular supports browsers included in the Baseline of a
76+
chosen date near the release date for that major.
77+
78+
The "widely available" Baseline includes browsers released less than 30 months (2.5 years)
79+
of the chosen date within Baseline's core browser set (Chrome, Edge, Firefox, Safari) and
80+
targets supporting approximately 95% of web users.
81+
82+
| Angular | Baseline Date | Browser Set |
83+
| ------- | ------------- | --------------------------- |
84+
| v21 | 2025-10-20 | [Browser Set][browsers-v21] |
85+
| v20 | 2025-04-30 | [Browser Set][browsers-v20] |
86+
87+
[browsers-v21]: https://web-platform-dx.github.io/web-features/supported-browsers/?widelyAvailableOnDate=2025-10-20&includeDownstream=false
88+
[browsers-v20]: https://web-platform-dx.github.io/web-features/supported-browsers/?widelyAvailableOnDate=2025-04-30&includeDownstream=false
89+
90+
Angular versions prior to v20 support the following specific browser versions:
91+
92+
| Browser | Supported versions |
93+
| :------ | :------------------------------------------ |
94+
| Chrome | 2 most recent versions |
95+
| Firefox | latest and extended support release \(ESR\) |
96+
| Edge | 2 most recent major versions |
97+
| Safari | 2 most recent major versions |
98+
| iOS | 2 most recent major versions |
99+
| Android | 2 most recent major versions |
100+
101+
## Polyfills
102+
103+
Angular is built on the latest standards of the web platform.
104+
Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.
105+
You compensate by loading polyfill scripts \("polyfills"\) for the browsers that you must support.
106+
See instructions on how to include polyfills into your project below.
107+
108+
IMPORTANT: The suggested polyfills are the ones that run full Angular applications.
109+
You might need additional polyfills to support features not covered by this list.
110+
111+
HELPFUL: Polyfills cannot magically transform an old, slow browser into a modern, fast one.
112+
113+
## Enabling polyfills with CLI projects
114+
115+
The [Angular CLI](tools/cli) provides support for polyfills.
116+
If you are not using the CLI to create your projects, see [Polyfill instructions for non-CLI users](#polyfills-for-non-cli-users).
117+
118+
The `polyfills` options of the [browser and test builder](tools/cli/cli-builder) can be a full path for a file \(Example: `src/polyfills.ts`\) or,
119+
relative to the current workspace or module specifier \(Example: `zone.js`\).
120+
121+
If you create a TypeScript file, make sure to include it in the `files` property of your `tsconfig` file.
122+
123+
```json
124+
125+
{
126+
"extends": "./tsconfig.json",
127+
"compilerOptions": {
128+
...
129+
},
130+
"files": [
131+
"src/main.ts",
132+
"src/polyfills.ts"
133+
]
134+
...
135+
}
136+
```
137+
138+
## Polyfills for non-CLI users
139+
140+
If you are not using the CLI, add your polyfill scripts directly to the host web page \(`index.html`\).
141+
142+
For example:
143+
144+
<docs-code header="src/index.html" language="html">
145+
<!-- pre-zone polyfills -->
146+
<script src="node_modules/core-js/client/shim.min.js"></script>
147+
<script>
148+
/**
149+
* you can configure some zone flags which can disable zone interception for some
150+
* asynchronous activities to improve startup performance - use these options only
151+
* if you know what you are doing as it could result in hard to trace down bugs.
152+
*/
153+
// __Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
154+
// __Zone_disable_on_property = true; // disable patch onProperty such as onclick
155+
// __zone_symbol__UNPATCHED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
156+
/*
157+
* in Edge developer tools, the addEventListener will also be wrapped by zone.js
158+
* with the following flag, it will bypass `zone.js` patch for Edge.
159+
*/
160+
// __Zone_enable_cross_context_check = true;
161+
</script>
162+
<!-- zone.js required by Angular -->
163+
<script src="node_modules/zone.js/bundles/zone.umd.js"></script>
164+
<!-- application polyfills -->
165+
</docs-code>
