Format url with query (string or object), simple and fast, with the power of qs.

The typical usage of this library is building URL for Fetch API. It can be used both on server side and browser side.

const withQuery = require('with-query').default;

fetch(withQuery('https://api.github.com/search/repositories', {
  q: 'query',
  sort: 'stars',
  order: 'asc',
}))
.then(res => res.json())
.then((json) => {
  console.info(json);
})
.catch((err) => {
  console.error(err);
});

Installation

• npm

npm install with-query --save

• yarn

yarn add with-query

Usage

var withQuery = require('with-query').default;
var assert = require('assert');

const result1 = withQuery('http://example.com', {
  a: 1,
  b: 'hello',
});
assert.equal(result1, 'http://example.com?a=1&b=hello');

// Append and override the query in url
const result2 = withQuery('http://example.com?a=3&c=4&d=5', {
  a: 1,
  b: 'hello',
});
assert.equal(result2, 'http://example.com?a=1&c=4&d=5&b=hello');

// Hash is also supported
const result3 = withQuery('http://example.com?a=3&c=4&d=5#Append', {
  a: 1,
  b: 'hello',
});
assert.equal(result3, 'http://example.com?a=1&c=4&d=5&b=hello#Append');

// Remove hash
const result4 = withQuery('http://example.com?a=3&c=4&d=5#Append', {
  a: 1,
  b: 'hello',
}, { noHash: true });
assert.equal(result4, 'http://example.com?a=1&c=4&d=5&b=hello');

// with the power of qs
const result5 = withQuery('http://example.com?e[]=f', {
  a: {
    b: 'c',
  },
});
assert.equal(result5, 'http://example.com?e%5B0%5D=f&a%5Bb%5D=c');

// parseOpt and stringifyOpt for qs.parse and qs.stringify
// see https://github.com/ljharb/qs
const result6 = withQuery('http://example.com&e[]=f', {
  a: {
    b: 'c',
  },
}, {
  stringifyOpt: {
    encode: false,
  },
  parseOpt: {
    parseArray: false,
  },
});
assert.equal(result6, 'http://example.com&e[]=f?a[b]=c');
