lambda-runtimes

AWS Lambda runtimes

A list of officially AWS Lambda runtimes organized by name

Installation

npm i lambda-runtimes

Usage

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

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

lambda-runtimes exports five items:

• runtimes (object) - Lambda runtime strings, organized by runtime name
  • Example: runtimes.node[0] → nodejs14.x
  • Where appropriate, each runtime may include (lowcase normalized) aliases, e.g. runtimes.node === runtimes.nodejs === runtimes.['node.js']
• 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] → nodejs14.x)
• architecturesByRuntime (object) - list of Lambda CPU architectures supported by each runtime
  • Example: architecturesByRuntime['nodejs14.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: [ 'nodejs14.x', 'nodejs12.x' ],
    ...
  },
  runtimeList: [ 'nodejs14.x', 'nodejs12.x', ... ],
  runtimesByArchitecture: {
    arm64: [ 'nodejs14.x', 'nodejs12.x', ... ],
    x86_64: [ 'nodejs14.x', 'nodejs12.x', ... ]
  },
  architecturesByRuntime: {
    'nodejs14.x': [ 'arm64', 'x86_64' ],
    'nodejs12.x': [ 'arm64', 'x86_64' ],
    ...
  },
  aliases: {
    nodejs: 'node',
    ...
  },
  retiredRuntimes: {
    node: [ 'nodejs10.x', ... ],
    ...
  },
}
