Framework detection utility.

Detects which framework a specific website is using. The framework's build/dev commands, directories and server port are also returned.

The following frameworks are detected:

• Static site generators: Gatsby, Hugo, Jekyll, Next.js, Nuxt, Hexo, Gridsome, Docusaurus, Eleventy, Middleman, Phenomic, React-static, Stencil, Vuepress, Assemble, DocPad, Harp, Metalsmith, Roots, Wintersmith
• Front-end frameworks: create-react-app, Vue, Sapper, Angular, Ember, Svelte, Expo, Quasar
• Build tools: Parcel, Brunch, Grunt, Gulp

If you're looking for a way to run framework-info via CLI check the build-info project.

Additions and updates are welcome!

Example (Node.js)

import { listFrameworks, hasFramework, getFramework, getFrameworkById } from '@netlify/framework-info'

console.log(await listFrameworks({ projectDir: './path/to/gatsby/website' }))
// [
//   {
//     id: 'gatsby',
//     name: 'Gatsby',
//     category: 'static_site_generator',
//     dev: {
//       commands: ['gatsby develop'],
//       port: 8000,
//       pollingStrategies: [{ name: 'TCP' }]
//     },
//     build: {
//       commands: ['gatsby build'],
//       directory: 'public'
//     },
//     staticAssetsDirectory: "static",
//     env: { GATSBY_LOGGER: 'yurnalist' },
//     plugins: []
//   }
// ]

console.log(await listFrameworks({ projectDir: './path/to/vue/website' }))
// [
//   {
//     id: 'vue',
//     name: 'Vue.js',
//     category: 'frontend_framework',
//     dev: {
//       commands: ['npm run serve'],
//       port: 8080,
//       pollingStrategies: [{ name: 'TCP' }]
//     },
//     build: {
//       commands: ['vue-cli-service build'],
//       directory: 'dist'
//     },
//     env: {},
//     plugins: []

// ]

console.log(await hasFramework('vue', { projectDir: './path/to/vue/website' }))
// true

console.log(await getFramework('vue', { projectDir: './path/to/vue/website' }))
// {
//   id: 'vue',

//   dev: {
//     commands: ['npm run serve'],
//     port: 8080,
//     pollingStrategies: [{ name: 'TCP' }]

//   build: {
//     commands: ['vue-cli-service build'],
//     directory: 'dist'
//   },
//   env: {},

Installation

npm install @netlify/framework-info

Usage (Node.js)

listFrameworks(options?)

options: object?
Return value: Promise<object[]>

Options

projectDir

Type: string
Default value: process.cwd()

Path to the website's directory.

Return value

This returns a Promise resolving to an array of objects describing each framework. The array can be empty, contain a single object or several objects.

Each object has the following properties.

id

Type: string

Id such as "gatsby".

name

Type: string

Framework name such as "Gatsby".

category

Type: string

Category among "static_site_generator", "frontend_framework" and "build_tool".

dev

Type: object

Information about the dev command.

commands

Type: string[]

Dev command. There might be several alternatives.

port

Type: number

Server port.

pollingStrategies

Type: object[]

Polling strategies to use when checking if the dev server is ready.

build

Type: object

Information about the build command.

commands

Type: string[]

Build command. There might be several alternatives.

directory

Type: string

Relative path to the directory where files are built.

staticAssetsDirectory

Type: string

Directory where the framework stores static assets. Can be undefined.

env

Type: object

Environment variables that should be set when calling the dev command.

plugins

Type: string[]

A list of recommend Netlify build plugins to install for the framework.

hasFramework(frameworkId, options?)

options: object?
Return value: Promise<boolean>

Same as listFramework() except only for a specific framework and returns a boolean.

getFramework(frameworkId, options?)

options: object?
Return value: Promise<object>

Same as listFramework() except the framework is passed as argument instead of being detected. A single framework object is returned.

Usage (CLI)

$ framework-info [projectDirectory]

This prints the ids of each framework.

If known is found, unknown is printed.

Available flags:

• --long: Show more information about each framework. The output will be a JSON array.

Add or update a framework

Each framework is a JSON file in the /src/frameworks/ directory. For example:

{
  "id": "gatsby",
  "name": "Gatsby",
  "category": "static_site_generator",
  "detect": {
    "npmDependencies": ["gatsby"],
    "excludedNpmDependencies": [],
    "configFiles": ["gatsby-config.js"]
  },
  "dev": {
    "command": "gatsby develop",
    "port": 8000,
    "pollingStrategies": [{ "name": "TCP" }, { "name": "HTTP" }]
  },
  "build": {
    "command": "gatsby build",
    "directory": "public"
