qstring

Comprehensive lightweight query string parser and stringifier + free parsing/output of process.argv.

Features:

• import { stringify, parse, parseProcessArgs } from 'qstring' (or qstring/dist/ for es2015)
• stringify(object); -> string
• parse(queryString); -> object
• parseProcessArgs(process.argv); -> object
• toProcessArgs(object) -> string
• 164 SLOC (3.5KiB built vs 1.5KiB GZipped)
• Dependency free.
• Performant, less than 1ms for below object on a Dell D430 (2 cores, 1.2Gz, 2GB of RAM)

const object = {
  '': 'defaultParamValue',
  example: [123.5, 252.23, 3, 'gaben'],
  level1Name: 'name',
  level1: {
    title: 'level1',
    '@$^strange~)*': '@:~)',
    level2: {
      level3Args: [1, 2, 'c'],
      level3: [{
        level4: 'foo'
      }, , {
        level4: 'bar'
      }]
    }
  }
};

// Output below.

//for readability purposes, using a multiline
const queryString = `
  ?defaultParamValue
  &example[0]=123.5
  &example[1]=252.23
  &example[2]=3
  &example[3]=gaben
  &level1Name=name
  &level1.title=level1
  &level1.%40%24%5Estrange~)*=%40%3A~)
  &level1.level2.level3Args=1
  &level1.level2.level3Args=2
  &level1.level2.level3Args=c
  &level1.level2.level3[].level4=foo
  &level1.level2.level3[2].level4=bar
`.replace(/[\n\t ]/g, ''); //strip all newlines and tabs

const processArgs = `
  --defaultParam 
  --example[0]=123.5 
  --example[1]=252.23 
  --example[2]=3 
  --example[3]=gaben 
  --level1Name=name
