core-js-compat
package contains data about the necessity of core-js
modules and API for getting a list of required core-js modules by browserslist query.
import compat from 'core-js-compat';
const {
list, // array of required modules
targets, // object with targets for each module
} = compat({
targets: '> 1%', // browserslist query or object of minimum environment versions to support, see below
modules: [ // optional list / filter of modules - regex, sting or an array of them:
'core-js/actual', // - an entry point
'esnext.array.unique-by', // - a module name (or just a start of a module name)
/^web\./, // - regex that a module name must satisfy
],
exclude: [ // optional list / filter of modules to exclude, the signature is similar to `modules` option
'web.atob',
],
version: '3.22', // used `core-js` version, by default - the latest
});
console.log(targets);

targets
optiontargets
could be a browserslist
query or a targets object that specifies minimum environment versions to support:
// browserslist query:
'defaults, not IE 11, maintained node versions'
// object:
{
android: '4.0', // Android WebView version
chrome: '38', // Chrome version
deno: '1.12', // Deno version
edge: '13', // Edge version
electron: '5.0', // Electron framework version
firefox: '15', // Firefox version
ie: '8', // Internet Explorer version
ios: '13.0', // iOS Safari version
node: 'current', // NodeJS version, you could use 'current' for set it to currently used
opera: '12', // Opera version
opera_mobile: '7', // Opera Mobile version
phantom: '1.9', // PhantomJS headless browser version
rhino: '1.7.13', // Rhino engine version
safari: '14.0', // Safari version
samsung: '14.0', // Samsung Internet version
esmodules: true, // That option set target to minimum supporting ES Modules versions of all browsers
browsers: '> 0.25%', // Browserslist query or object with target browsers
}
// equals of of the method from the example above
require('core-js-compat/compat')({ targets, modules, version }); // => { list: Array<ModuleName>, targets: { [ModuleName]: { [EngineName]: EngineVersion } } }
// or
require('core-js-compat').compat({ targets, modules, version }); // => { list: Array<ModuleName>, targets: { [ModuleName]: { [EngineName]: EngineVersion } } }
// full compat data:
require('core-js-compat/data'); // => { [ModuleName]: { [EngineName]: EngineVersion } }
// or
require('core-js-compat').data; // => { [ModuleName]: { [EngineName]: EngineVersion } }
// map of modules by `core-js` entry points:
require('core-js-compat/entries'); // => { [EntryPoint]: Array<ModuleName> }
// or
require('core-js-compat').entries; // => { [EntryPoint]: Array<ModuleName> }
// full list of modules:
require('core-js-compat/modules'); // => Array<ModuleName>
// or
require('core-js-compat').modules; // => Array<ModuleName>
// the subset of modules which available in the passed `core-js` version:
require('core-js-compat/get-modules-list-for-target-version')('3.22'); // => Array<ModuleName>
// or
require('core-js-compat').getModulesListForTargetVersion('3.22'); // => Array<ModuleName>
If you want to add new / update data about modules required for target engines, follow this instruction.
