npm i lambda-runtimes

// esm import { runtimes, runtimeVersions, runtimeList, runtimesByArchitecture, architecturesByRuntime, aliases, retiredRuntimes, } from 'lambda-runtimes'

// cjs let { runtimes, runtimeVersions, runtimeList, runtimesByArchitecture, architecturesByRuntime, aliases, retiredRuntimes, } = require('lambda-runtimes')

lambda-runtimes exports seven items:

• runtimes (object) - Lambda runtime strings, organized by runtime name
  • Example: runtimes.node[0] → nodejs20.x
  • Where appropriate, each runtime may include (lowcase normalized) aliases, e.g. runtimes.node === runtimes.nodejs === runtimes.['node.js']
• runtimeVersions (object) - Semver representations of each Lambda runtime
  • Example: runtimeVersions['nodejs20.x'] returns an object with major: '20', minor: null, patch: null, and wildcard: '20.*.*' properties
• runtimeList (array) - list of all Lambda runtime strings (order not necessarily guaranteed)
• runtimesByArchitecture (object) - list of Lambda runtimes supported by each CPU architecture
  • Example: runtimesByArchitecture.arm64[0] → nodejs20.x)
• architecturesByRuntime (object) - list of Lambda CPU architectures supported by each runtime
  • Example: architecturesByRuntime['nodejs20.x'] → [ 'arm64', 'x86_64' ])
• aliases (object) - shorthand or alternate names for runtime aliases (e.g. py for python)
• retiredRuntimes (object) - retired / EOL Lambda runtime strings, organized by runtime name
  • Example: retiredRuntimes.node[0] → nodejs10.x

Example:

{ runtimes: { node: [ 'nodejs20.x', 'nodejs18.x' ], ... }, runtimeVersions: { 'nodejs20.x': { major: '20', minor: null, patch: null, wildcard: '20.*.*' }, ... }, runtimeList: [ 'nodejs20.x', 'nodejs18.x', ... ], runtimesByArchitecture: { arm64: [ 'nodejs20.x', 'nodejs18.x', ... ], x86_64: [ 'nodejs20.x', 'nodejs18.x', ... ] }, architecturesByRuntime: { 'nodejs20.x': [ 'arm64', 'x86_64' ], 'nodejs18.x': [ 'arm64', 'x86_64' ], ... }, aliases: { nodejs: 'node', ... }, retiredRuntimes: { node: [ 'nodejs10.x', ... ], ... }, }
