Node.js ECMAScript Compatibility

API for the Node.js ECMAScript Compatibility information, such that for a particular Node.js release, you get details on which and how many features of an ECMAScript version are supported.

Usage

Complete API Documentation.

import {
    fetchNodeVersionCompatibility,
    fetchNodeVersionsCompatibility,
    fetchMutualCompatibleESVersionsForNodeVersions,
    fetchExclusiveCompatibleESVersionsForNodeVersions,
    fetchAllCompatibleESVersionsForNodeVersions,
} from '@bevry/nodejs-ecmascript-compatibility'

// fetch the compatibility information for the current node.js version
fetchNodeVersionCompatibility().then(console.log)

// fetch the details for a specific node.js version
fetchNodeVersionCompatibility('4.9.1').then(console.log)

// fetch the details for multiple node.js versions
fetchNodeVersionsCompatibility(['4.9.1', '12.0.0']).then(console.log)

// fetch each ECMAScript version that supports both releases
fetchMutualCompatibleESVersionsForNodeVersions(['4.9.1', '12.0.0']).then(
    console.log,
)

// fetch the minimum ECMAScript versions required to support both releases
fetchExclusiveCompatibleESVersionsForNodeVersions(['4.9.1', '12.0.0']).then(
    console.log,
)

// fetch each ECMAScript version that supports either release
fetchAllCompatibleESVersionsForNodeVersions(['4.9.1', '12.0.0']).then(
    console.log,
)

Node.js versions 15 and 16 will need to use --experimental-global-fetch.
