The config to share target browsers and Node.js versions between different
|
|
|
front-end tools. It is used in:
|
|
|
|
|
|
* [Autoprefixer]
|
|
|
* [Babel]
|
|
|
* [postcss-preset-env]
|
|
|
* [eslint-plugin-compat]
|
|
|
* [stylelint-no-unsupported-browser-features]
|
|
|
* [postcss-normalize]
|
|
|
* [obsolete-webpack-plugin]
|
|
|
|
|
|
All tools will find target browsers automatically,
|
|
|
when you add the following to `package.json`:
|
|
|
|
|
|
```json
|
|
|
"browserslist": [
|
|
|
"defaults",
|
|
|
"not IE 11",
|
|
|
"maintained node versions"
|
|
|
]
|
|
|
```
|
|
|
|
|
|
Or in `.browserslistrc` config:
|
|
|
|
|
|
```yaml
|
|
|
# Browsers that we support
|
|
|
|
|
|
defaults
|
|
|
not IE 11
|
|
|
maintained node versions
|
|
|
```
|
|
|
|
|
|
Developers set their version lists using queries like `last 2 versions`
|
|
|
to be free from updating versions manually.
|
|
|
Browserslist will use [`caniuse-lite`] with [Can I Use] data for this queries.
|
|
|
|
|
|
Browserslist will take queries from tool option,
|
|
|
`browserslist` config, `.browserslistrc` config,
|
|
|
`browserslist` section in `package.json` or environment variables.
