This library allows :
- Create URLs most easly
- Parse and decompose your URLs
- Ride up in the URL tree
- Make comparisons between URLs
To import the library you just need to run this command :
npm install @innova2/url-builder
const url = UrlBuilder.createFromUrl('http://localhost:8080/users');
// or
const url = UrlBuilder.createFromUrl('/users', 'http://localhost:8080');
// or create new url with the constructor
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'
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'
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' }
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
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.
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'
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'
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'
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'
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 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
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
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 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 to create file object containing 'name' and 'ext' (extension). Works with any extension (no verification).
UrlUtils.parseFile('image.png'); // Output: { name: 'image', ext: 'png' }
