📑 Features

This library allows :

  • Create URLs most easly
  • Parse and decompose your URLs
  • Ride up in the URL tree
  • Make comparisons between URLs

🛠️ Installation

To import the library you just need to run this command :

npm install @innova2/url-builder

📝 Usage

Create from existing URL

const url = UrlBuilder.createFromUrl('http://localhost:8080/users');
// or create new url with the constructor

Handle path

Add new path segment(s) and params

[!NOTE] All methods (except getBaseUrl) on PathParams object (by getPathParams()), return the current PathParams object and not the current UrlBuilder object [!NOTE] The add() and addAll() methods on PathParams object does not add the entry if the key already exists. Use set() or setAll() instead

const userId = '170b16cd-ad47-4c9c-86cf-7c83bd40d775';
url.addPath(':id/comments').getPathParams().add('id', userId);
// Or
url.addPath(':id/comments', { id: userId });

Add multiples parameters after adding path segment(s)

const userId = '170b16cd-ad47-4c9c-86cf-7c83bd40d775';
const commentId = '218dd1c4-0bb0-425a-be0b-85427304e100';
url.addPath(':userId/comments/:commentId').getPathParams().addAll({ userId, commentId });
// Or
url.addPath(':userId/comments/:commentId', { userId, commentId });

If you want to add or replace existing param(s), use instead :

const userId = '170b16cd-ad47-4c9c-86cf-7c83bd40d775';
const commentId = '218dd1c4-0bb0-425a-be0b-85427304e100';
url.addPath(':userId/comments/:commentId', { userId: 3, commentId: 1 });

// Without replacement :
url.getPathParams().add('userId', userId);
// Param 'userId' is always : 3

// With replacement :
url.getPathParams().set('userId', userId);
// Param 'userId' is now : 170b16cd-ad47-4c9c-86cf-7c83bd40d775


// Or with multiples parameters
// Without replacement :
url.getPathParams().addAll({ userId: 10, commentId: 5 });
// Param 'userId' is always : 170b16cd-ad47-4c9c-86cf-7c83bd40d775
// Param 'commentId' is always : 1

// With replacement :
url.getPathParams().setAll({ userId: 10, commentId: 5 });
// Param 'userId' is now : 10
// Param 'commentId' is now : 5

Retrieve params

const url = new UrlBuilder()
    .getPathParams().addAll({
      startDate: '1679737680454',
      endDate: '1679937680454',
    });

const params = url.getPathParams();
// params contains all path params as Map

const filteredParams = url.getPathParams().filter(([key, value]) => new Date(Number(value)).getDate() === 25);
// filteredParams contains a new Map only with param 'startDate'

Get the first path segment

const rowNum = 10;
const url = UrlBuilder.createFromUrl('http://localhost:8080/rows/:rowNum/cells').addParam('rowNum', rowNum);
url.getFirstPath(); // Output: 'rows'

Get the last path segment

url.getLastPath(); // Output: 'cells'

Delete some path params

const url = new UrlBuilder()
    .getPathParams().addAll({
      startDate: '1679737680454',
      endDate: '1679937680454',
    });

url.getPathParams().deleteBy(([key, value]) => new Date(Number(value)).getDate() === 25);
// PathParams no longer contains param 'endDate'

Handle query param

[!NOTE] All methods (except getBaseUrl) on QueryParams object (by getQueryParams()), return the current QueryParams object and not the current UrlBuilder object

[!NOTE] The add() and addAll() methods on QueryParams object does not add the entry if the key already exists. Use set() or setAll() instead Add new query param

const page = 2;
url.getQueryParams().add('page', page);

// or
url.addQueryParam('page', page);

Add multiples query params

const page = 2;
const order = 'DESC';
url.getQueryParams().addAll({ page, order });

If you want to add or replace existing query, use instead :

const page = 2;
const order = 'DESC';
url.getQueryParams().addAll({ page, order });

// Without replacement :
url.getQueryParams().add('page', 3);
// QueryParam 'page' is always : 2

// With replacement :
url.getQueryParams().set('page', 3);
// QueryParam 'page' is now : 3


// Or with multiples parameters
// Without replacement :
url.getQueryParams().addAll({ page: 4, order: 'ASC' });
// QueryParam 'page' is always : 3
// QueryParam 'order' is always : DESC

// With replacement :
url.getQueryParams().setAll({ page: 4, order: 'ASC' });
// QueryParam 'page' is now : 4
// QueryParam 'order' is now : ASC

Retrieve query params

const url = new UrlBuilder()
    .getQueryParams().addAll({
      style: 'dark',
      utm_source: 'Google',
      utm_medium: 'newsletter',
      utm_campaign: 'summer',
      isMobile: 1
    });

const queryParams = url.getQueryParams();
// queryParams contains all query params as Map

const filteredQueryParams = url.getQueryParams().filter(([key]) => key.startsWith('utm'));
// filteredQueryParams contains a new Map only with query params 'utm_source', 'utm_medium' and 'utm_campaign'

Delete some query params

const url = new UrlBuilder()
    .getQueryParams().addAll({
      style: 'dark',
      utm_source: 'Google',
      utm_medium: 'newsletter',
      utm_campaign: 'summer',
      isMobile: 1
    });

url.getQueryParams().deleteBy(([key]) => key.startsWith('utm'));
// QueryParams no longer contains query params 'utm_source', 'utm_medium' and 'utm_campaign'

Handle file

Parse file in url

// Consider file part of path segments
const url = UrlBuilder.createFromUrl('http://localhost/users/10.html');
url.getRelativePath();
// Output : /users/10.html
url.getPathSegments();
// Output : ['users', '10.html'];
url.getFile();
// Output : undefined

// Consider file dissociated of path segments
const url2 = UrlBuilder.createFromUrl('http://localhost/users/10.html', true);
url2.getRelativePath();
// Output : /users/10.html
url2.getPathSegments();
// Output : ['users'];
url2.getFile();
// Output : { name: '10', ext: 'html' }

Define file

url.setFile({ name: 'mycover', ext: 'webp' });
url.getFile();
// Output : { name: 'mycover', ext: 'webp' }

Define file from filename

url.setFilename('mycover.webp');
url.getFile();
// Output : { name: 'mycover', ext: 'webp' }

Handle fragment

Parse fragment with url

const url = UrlBuilder.createFromUrl('http://localhost/users?page=1#foo');
url.getRelativePath(false, true);
// Output : /users#foo
// The first boolean is "withQuery" and the seconde is "withFragment"
// With query params and fragment :
url.getRelativePath(true, true);
// Output : /users?page=1#foo

Define fragment without hash

url.setFragment('bar');

Retrieve fragment

const fragment = url.getFragment();
// Output : bar
url.getRelativePath(false, true);
// Output : /users#bar

Merge path and query params

It's possible to merge path and query params with another url

const url = UrlBuilder.createFromUrl('http://localhost:3000').addPath('groups');

const anotherUrl = new UrlBuilder()
    .addPath(':id/users', { id: 2 })
    .addQueryParam('page', 1)

url.mergePathWith(anotherUrl).toString() // Get 'http://localhost:3000/groups/2/users?page=1'

Note : This function merge only path, params and query params with current url.

Work with parent

Get parent URL easly.
This function return a new instance of UrlBuilder

const url = UrlBuilder.createFromUrl('http://localhost:8080/orders/:orderId/products/:productId');
const parent = url.getParent(); // Get 'http://localhost:8080/orders/:orderId/products'

Or up to the specific level

url.getParent(3); // Get 'http://localhost:8080/orders'

Get relative path

Retrieve the relative path as string format

const postId = 'a937b39e-9664-404a-ac56-f3da2b83a951';
const url = UrlBuilder.createFromUrl('http://localhost:8080/posts/:id').addParam('id', postId);
url.getRelativePath(); // Output: '/posts/a937b39e-9664-404a-ac56-f3da2b83a951'

And with query params
Don't forget to add 'true' parameter to allow query params conversion

url.addQueryParam('displaySimilar', true);
url.getRelativePath(); // Output: '/posts/a937b39e-9664-404a-ac56-f3da2b83a951'
url.getRelativePath(true); // Output: '/posts/a937b39e-9664-404a-ac56-f3da2b83a951?displaySimilar=true'

Get query params as string

Retrieve the query params as string format

const queryParams = UrlBuilder.createFromUrl('http://localhost:8080/vehicles').getQueryParams().setAll({
  page: 2,
  order: 'ASC',
});
queryParams.toString(); // Output: '?page=2&order=ASC'

Convert full URL to string

Retrieve the query params as string format

const name = 'url-builder';
const url = UrlBuilder.createFromUrl('https://github.com/InnovA2')
        .addPath(':name/pulls')
        .addParam('name', name);
url.toString(); // Output: 'https://github.com/InnovA2/url-builder/pulls'

📝 Advanced

Compare URL to another

Compare the current URL to another URL (UrlBuilder instance)

const id = '434f65eb-4e5f-4b29-899c-b3e159fff61c';
const id2 = '3e972ca2-b422-4ac9-b793-e6f305c7bfb2';
const url = UrlBuilder.createFromUrl('http://localhost:8080/users/:id').addParam('id', id);
const url2 = UrlBuilder.createFromUrl('http://localhost:8080/users/:id').addParam('id', id);
const url3 = UrlBuilder.createFromUrl('http://localhost:8080/users/:id').addParam('id', id2);
url.compareTo(url2); // Output: true
url.compareTo(url3); // Output: false

Compare relative path to another by segment

Compare the path segments of the current URL to another relative path

const url: UrlBuilder = UrlBuilder.createFromUrl('/users/10/comments');
url.compareToPathBySegment('/users/10/comments') // Output: true
const url2: UrlBuilder = UrlBuilder.createFromUrl('/users/:id/comments');
url2.compareToPathBySegment('/users/10/comments') // Output: false
const url3: UrlBuilder = UrlBuilder.createFromUrl('/users/:id/comments').addParam('id', 10);
url3.compareToPathBySegment('/users/10/comments') // Output: true
// Or, validate unfilled params
const url4: UrlBuilder = UrlBuilder.createFromUrl('/users/:id/comments');
url4.compareToPathBySegment('/users/10/comments', true) // Output: true

Get path between two segments

const url = UrlBuilder.createFromUrl('http://localhost:8080/users/10/comments');
url.getBetween2Segments('users', 'comments'); // Output: 10

const url2 = UrlBuilder.createFromUrl('http://localhost:8080/users/10/comments/5');
url2.getBetween2Segments('users', '5'); // Output: 10/comments

📝 Utils

Split path from string

Split path string by slash

UrlUtils.splitPath('/InnovA2/url-builder/pulls/'); // Output: ['InnovA2', 'url-builder', 'pulls']
// or if you have more slashes
UrlUtils.splitPath('/InnovA2///url-builder/pulls/'); // Output: ['InnovA2', 'url-builder', 'pulls']

Trim path from string

Trim path string by removing useless slashes

UrlUtils.trimPath('/InnovA2/url-builder/pulls/'); // Output: 'InnovA2/url-builder/pulls'
// or if you have more slashes
UrlUtils.trimPath('/InnovA2///url-builder/pulls/'); // Output: 'InnovA2/url-builder/pulls'

Parse filename

Parse filename to create file object containing 'name' and 'ext' (extension). Works with any extension (no verification).

UrlUtils.parseFile('image.png'); // Output: { name: 'image', ext: 'png' }
