Installation

npm

npm i @hom3chuk/tektek

yarn

yarn add @hom3chuk/tektek

Usage

Import

commonjs

const tektek = require('@hom3chuk/tektek')
const fs = require('fs')

const detect = tektek.detect

const har = JSON.parse(fs.readFileSync('example.har').toString())

const de = detect(har)

console.log(de)

module

import { detect } from '@hom3chuk/tektek'
import * as fs from 'fs'

const har = JSON.parse(fs.readFileSync('example.har').toString())

const de = detect(har)

console.log(de)

Options

You can run detect with additional options:

import { detect } from '@hom3chuk/tektek'
import * as fs from 'fs'

const har = JSON.parse(fs.readFileSync('example.har').toString())

const de = detect(har, {
    asap: false,
    foundOnly: false,
})

console.log(de)

asap

Default is true

Setting asap to true will prevent detectors from running through all of the rules as soon as the first match is found. Useful when you want a binary result for each technology. Each detector will return at most one reason:

[
  {
    detected: true,
    name: 'Shopify',
    reasons: [ 'has preload header' ]
  }
]

Setting asap to false will enforce detectors to run through all of the rules, even after the first match. Useful when you need as extensive of a profile as defined by the rules. Each detector can return multiple reasons:

[
  {
    detected: true,
    name: 'Shopify',
    reasons: [ 'has preload header', 'has powered-by header' ]
  }
]

foundOnly

Default is true

Setting foundOnly to true will filter the results to only contain entries with positive detections:

[
  {
    detected: true,
    name: 'Shopify',
    reasons: [ 'has preload header' ]
  }
]

Setting foundOnly to false will return all of the detectors results available, even those that were not found:

[
  { detected: false, name: 'Akamai Net Storage', reasons: [] },
  { detected: false, name: 'nginx', reasons: [] },
  {
    detected: true,
    name: 'Shopify',
    reasons: [ 'has preload header' ]
  }
]
