## Installation ## Usage
bigint-mod-arith is distributed for [web browsers and/or webviews supporting BigInt](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt#Browser_compatibility) as an ES6 module or an IIFE file; and for Node.js (>=10.4.0), as a CJS module. `bigint-mod-arith` can be imported to your project with `npm`:
bigint-mod-arith can be imported to your project with `npm`: ```console
```bash
npm install bigint-mod-arith npm install bigint-mod-arith
``` ```
NPM installation defaults to the ES6 module for browsers and the CJS one for Node.js. For web browsers, you can also directly download the [IIFE bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/lib/index.browser.bundle.iife.js) or the [ESM bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/lib/index.browser.bundle.mod.js) from the repository. Then either require (Node.js CJS):
## Usage example
Import your module as :
- Node.js
```javascript ```javascript
const bigintModArith = require('bigint-mod-arith') const bigintModArith = require('bigint-mod-arith')
... // your code here
``` ```
- JavaScript native or TypeScript project (including React and Angular)
or import (JavaScript ES module):
```javascript ```javascript
import * as bigintModArith from 'bigint-mod-arith' import * as bigintModArith from 'bigint-mod-arith'
... // your code here
```
- JavaScript native browser ES module
```html
<script type="module">
import * as bigintModArith from 'lib/index.browser.bundle.mod.js' // Use you actual path to the broser mod bundle
... // your code here
</script>
```
- JavaScript native browser IIFE
```html
<head>
...
<script src="../../lib/index.browser.bundle.iife.js"></script> <!-- Use you actual path to the browser bundle -->
</head>
<body>
...
<script>
... // your code here
</script>
</body>
``` ```
The appropriate version for browser or node is automatically exported.
You can also download the [IIFE bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/dist/bundles/bigint-mod-arith.iife.js), the [ESM bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/dist/bundles/bigint-mod-arith.esm.js) or the [UMD bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/dist/bundles/bigint-mod-arith.umd.js) and manually add it to your project, or, if you have already imported `bigint-mod-arith` to your project, just get the bundles from `node_modules/bigint-mod-arith/dist/bundles/`.
An example of usage could be: An example of usage could be:
```javascript ```typescript
/* Stage 3 BigInts with value 666 can be declared as BigInt('666') /* Stage 3 BigInts with value 666 can be declared as BigInt('666')
or the shorter syntax 666n. or the shorter syntax 666n.

## Installation ## Usage
{{PKG_NAME}} is distributed for [web browsers and/or webviews supporting BigInt](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt#Browser_compatibility) as an ES6 module or an IIFE file; and for Node.js (>=10.4.0), as a CJS module. `{{PKG_NAME}}` can be imported to your project with `npm`:
{{PKG_NAME}} can be imported to your project with `npm`: ```console
```bash
npm install {{PKG_NAME}} npm install {{PKG_NAME}}
``` ```
NPM installation defaults to the ES6 module for browsers and the CJS one for Node.js. For web browsers, you can also directly download the {{IIFE_BUNDLE}} or the {{ESM_BUNDLE}} from the repository. Then either require (Node.js CJS):
## Usage example
Import your module as :
- Node.js
```javascript ```javascript
const {{PKG_CAMELCASE}} = require('{{PKG_NAME}}') const {{PKG_CAMELCASE}} = require('{{PKG_NAME}}')
... // your code here
``` ```
- JavaScript native or TypeScript project (including React and Angular)
or import (JavaScript ES module):
```javascript ```javascript
import * as {{PKG_CAMELCASE}} from '{{PKG_NAME}}' import * as {{PKG_CAMELCASE}} from '{{PKG_NAME}}'
... // your code here
```
- JavaScript native browser ES module
```html
<script type="module">
import * as {{PKG_CAMELCASE}} from 'lib/index.browser.bundle.mod.js' // Use you actual path to the broser mod bundle
... // your code here
</script>
```
- JavaScript native browser IIFE
```html
<head>
...
<script src="../../lib/index.browser.bundle.iife.js"></script> <!-- Use you actual path to the browser bundle -->
</head>
<body>
...
<script>
... // your code here
</script>
</body>
``` ```
The appropriate version for browser or node is automatically exported.
You can also download the {{IIFE_BUNDLE}}, the {{ESM_BUNDLE}} or the {{UMD_BUNDLE}} and manually add it to your project, or, if you have already imported `{{PKG_NAME}}` to your project, just get the bundles from `node_modules/{{PKG_NAME}}/dist/bundles/`.
An example of usage could be: An example of usage could be:
```javascript ```typescript
/* Stage 3 BigInts with value 666 can be declared as BigInt('666') /* Stage 3 BigInts with value 666 can be declared as BigInt('666')
