depseek

Seeks for dependency references in JS/TS code

lcov npm

Motivation

Dep extraction is a common task for many tools solved in different ways from regexps to AST parsing. This implementation relies on streams, which should significantly reduce memory consumption.

Status

PoC

Key features

  • Streams instead of RegExp or AST parsing
  • Specifies exact code references by offset
  • Handles string literal and comment boundaries
  • Captures bound comments (optional)

Usage

npm i depseek

Usage

import fs from 'fs'
import {depseek} from 'depseek'

const stream = fs.createReadStream('index.js')
const deps = await depseek(stream)

// returns
[
  { type: 'dep', value: 'node:fs', index: 17 },
  { type: 'dep', value: 'foo', index: 34 },
  { type: 'dep', value: 'q', index: 92 }
  // ...
]
