JSPM

Use custom cursors in your HTML, CSS & JavaScript application (Browser & NodeJs).

• Simple and easy to use.
• Can also be used in your own application.
• Primarily uses tochiResources cursors, use your own cursors instead if necessary.
• Works in both NodeJs and Browser contexts (read more below).

You must use something like for Browser contexts if require doesn't work.

Demo

See live demo here

Install

npm i @tochiresources/cursors

Examples

JavaScript

CommonJs require

const cursors = require('@tochiresources/cursors');

Use multiContext to enable multicontextual support eg. NodeJs and Browser contexts at the same time.

• Enabling this will prioritize Browser context.

cursors.multiContext(true);

(NodeJs) Apply once for all elements with apply.

// simple
cursors.apply('./css/styles.css', './css');

// with more arguments
cursors.apply('./css/styles.css', './css', cursors.CursorSize.small, cursors.CursorColor.white, 200);

// with more arguments and custom cursors
cursors.applySelectors('./css/styles.css', './css', cursors.CursorSize.small, null, 200, { // color will be ignored when using custom options
  // override directory path
  // custom cursors should be placed in respective cursor size folder structure eg. 32x32/cursor.png, 64x64/cursor.png and 128x128/cursor.png
  cursorDir: "./test/cursors", // directory path containing cursor size folders (relative to the outputFolder if you change this)

  // override all available cursors
  default: { name: "pointer", offset: new CursorOffset(3, 3) },
  pointer: { name: "link", offset: new CursorOffset(5, 2) },
  text: { name: "beam", offset: new CursorOffset(16, 16) },
  progress: { name: "working", offset: new CursorOffset(3, 3) },
  wait: { name: "busy", offset: new CursorOffset(16, 16) },
  allScroll: { name: "move", offset: new CursorOffset(16, 16) },
  ewResize: { name: "horz", offset: new CursorOffset(16, 16) },
  nsResize: { name: "vert", offset: new CursorOffset(16, 16) },
  neswResize: { name: "dgn2", offset: new CursorOffset(16, 16) },
  nwseResize: { name: "dgn1", offset: new CursorOffset(16, 16) }
});

(Browser) Apply once for all elements with applyWeb.

// simple
cursors.applyWeb('css/styles.css');

// with more arguments
cursors.applyWeb('css/styles.css', cursors.CursorSize.small, cursors.CursorColor.white, 200);

// with more arguments and custom cursors
cursors.applySelectorsWeb('css/styles.css', cursors.CursorSize.small, null, 200, { // color will be ignored when using custom options
  // override directory path
  // custom cursors should be placed in respective cursor size folder structure eg. 32x32/cursor.png, 64x64/cursor.png and 128x128/cursor.png
  cursorDir: "<your-root-folder>/bin/cursors", // directory path containing cursor size folders (absolute path is recommended)

  // override all available cursors
  default: { name: "pointer", offset: new CursorOffset(3, 3) },
  pointer: { name: "link", offset: new CursorOffset(5, 2) },
  ...
});

(NodeJs) Apply for individual elements with applySelectors.

// simple
cursors.applySelectors('./css/styles.css', './css', '#logo, .tab, .drop-zone');

// with more arguments
cursors.applySelectors('./css/styles.css', './css', '#logo, .tab, .drop-zone', cursors.CursorSize.small, cursors.CursorColor.white);

// with more arguments and custom cursors
cursors.applySelectors('./css/styles.css', './css', '#logo, .tab, .drop-zone', cursors.CursorSize.small, null, {
  cursorDir: "./bin/cursors",
  default: { name: "custom1", offset: new CursorOffset(3, 3), },
  pointer: { name: "custom2", offset: new CursorOffset(5, 3), },
  ...
});

(Browser) Apply for individual elements with applySelectorsWeb.

// simple
cursors.applySelectorsWeb('css/styles.css', '#logo, .tab, .drop-zone');

// with more arguments
cursors.applySelectorsWeb('css/styles.css', '#logo, .tab, .drop-zone', cursors.CursorSize.small, cursors.CursorColor.white);

// with more arguments and custom cursors)
cursors.applySelectorsWeb('css/styles.css', '#logo, .tab, .drop-zone', cursors.CursorSize.small, null, {
  cursorDir: "./bin/cursors",
  default: { name: "custom1", offset: new CursorOffset(3, 3), },
  pointer: { name: "custom2", offset: new CursorOffset(5, 3), },
  ...
});

In case you're confused about the difference between these methods:

• NodeJs
  • Use apply to automatically apply cursors on relevant semantic HTML tags and selectors.
  • Use applySelectors to apply cursors on specified selectors only.
• Browser
  • applyWeb same as NodeJs but only works in Browser context.
  • applySelectorsWeb same as NodeJs but only works in Browser context.

CSS

You can apply cursor styles normally in your css file like:

.selectorClass div {
  cursor: text;
}

#selectorId a:hover {
  cursor: pointer;
}

and then the selector's cursor property will automatically be converted to a tochiResources cursor.

See supported cursor types down below or .

Please take a look at the API below for more details.

How it works

When using apply(styleSheetUrl, size, color, delay, options):

1. Apply cursors on semantic HTML tags eg. button and a.
2. Find css file (styleSheetUrl) and read it's contents.
3. Find rules from css file contents with a cursor property and then obtain the selectors and cursor value.
4. Apply cursors on obtained data.

When using applySelectors(styleSheetUrl, selectors, size, color, options):

1. Find css file (styleSheetUrl) and read it's contents.
2. Find specified selectors from css file contents, check if the rules contains a cursor property and then obtain the selectors and cursor value.
3. Apply cursors on obtained data.

As you can see applySelectors skips semantic HTML tags and only focues on specified selectors.

• This approach allows a lightweight process and performs faster than using querySelector to apply cursors on HTML elements.
• The latter have been tested and performs extremely poorly.
• HTML elements' applied cursor property won't be overridden if changed through JavaScript because of the generated internal style tag (Browser) or the generated css file (NodeJs).

Output

• You can see how the css will look like by checking out .
• A .css file will be generated when using this in NodeJs context.
• A HTML <style> tag will be created/appended inside the <head> tag in Browser context.

Performance may become a concern if:

• Specified css file (styleSheetUrl) exceeds more than 2000 lines (not tested above this limit).

CssScanner

• This module uses to scan through specified css file (styleSheetUrl).

Notes

[!IMPORTANT] You don't need to specify a cursor property for semantic HTML tags. They will automatically be applied accordingly if you use apply or applyWeb. To include other HTML tags or elements they must require a valid class or id attribute and be referenced in your css file (styleSheetUrl).

[!NOTE] Dynamic sites:

May not work on dynamically added elements but that's when you can use the cursor.applySelectors('css/styles.css', selectors) function to apply cursors on specified elements.

Cursor sizes:

Most browsers won't support cursor sizes above small which is 32 x 32.
