# Skeleton for both Node.js and native JS modules
Clone this repo to your desired project directory (`my-project` in the following example), unlink the git, install the required development dependencies and start working.
```bash
git clone https://github.com/juanelas/node-browser-skel.git my-project
cd my-project
rm -rf .git .gitignore lib/.gitignore test/browser/.gitignore types/.gitignore README.md
npm i -D rollup @rollup/plugin-commonjs @rollup/plugin-multi-entry @rollup/plugin-node-resolve @rollup/plugin-replace chai jsdoc-to-markdown mocha npm-run-all rollup-plugin-terser standard typescript
```
A new JS project is created and it is ready to bundle IIFE, ESM and CJS modules with the corresponding declaration files for TypeScript. Code follows [JavaScript Standard](https://standardjs.com) style. The bundles are created with [Rollup](https://rollupjs.org).
A structure like the following is going to be created:
```
.
├── build/
│   ├── build.dts.js
│   ├── rollup.config.js
│   └── rollup.tests.config.js
├── INSTRUCTIONS.md
├── lib/
├── LICENSE
├── package.json
├── src/
│   ├── browser/
│   │   └── tests-template.html
│   ├── doc/
│   │   └── readme-template.md
│   └── js/
│   └── index.js
├── test/
│   ├── browser/
│   └── test1.js
└── types/
```
The file `INSTRUCTIONS.md` contains a copy of what you are reading now. You can safely delete it when you don't need it any more.
## Init your project
Edit `package.json` to suit your needs and initialize the project with:
```bash
npm install
npm run build
```
The `README.md` file of your project will be created during the build process, DO NOT EDIT it; edit `./src/doc/readme-template.md` instead. The JS Doc will be automatically added to the end of the `README.md`.
After editing `./src/doc/readme-template.md`, you can build your `README.md` as:
```
npm run build:docs
```
## Write JS code and build for node.js and native browsers
Write your code in ES6 using file `./src/js/index.js`. You can use boolean variable `process.browser` to create specific code for native JS or Node. For example:
```javascript
if (process.browser) {
// browser specific code here
} else {
// node.js specific code here
}
```
Once your source code is ready, you can build the final browser/node files (the node.js specific code will be stripped from the browser final files and vice versa) as:
```bash
npm run build:js
```
Final browser/node files include an ESM file, a bundle ESM file, and a bundle IIFE file for browsers; and a CJS module for node:
```
lib
├── index.browser.bundle.js
├── index.browser.bundle.mod.js
├── index.browser.mod.js
└── index.node.js
```
A file with Typescript definition types can also be built to `./types/index.d.ts` with :
```
npm run build:dts
```
> Consider using JS Doc with your exports. If the JS doc includes typing in the documentation, the created types definition file will honour the JS doc typing instead of using `any` everywhere.
## Create and run tests for node.js and browser
Mocha/Chai tests are created using Node.js common js format and should be placed in directory `./test/`. You can create separate test files but follow the instructions in `./test/test1.js`.
You can run tests in Node.js with:
```bash
npm test
```
Browser tests are built from the node.js ones:
```
npm run build:browserTests
```
Don't forget rebuilding after adding/modifying a test.
> Opening the browser tests requires a local live server to serve `./test/browser/index.html`. With VSCode, you can use the [Live Server extension](https://marketplace.visualstudio.com/items?itemName=ritwickdey.LiveServer) and just right click over the file and `Open with Live Server`; although any other server solution should be fine.
## Build all in one step
You can just go through all the build steps in one step:
```
npm run build
```

# bigint-mod-arith
**IMPORTANT! This package has been superseded by [bigint-crypto-utils](https://github.com/juanelas/bigint-crypto-utils)**. Please install that package instead.
Some extra functions to work with modular arithmetics using native JS (stage 3) implementation of BigInt. It can be used by any [Web Browser or webview supporting BigInt](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt#Browser_compatibility) and with Node.js (>=10.4.0).
If you are also looking for a cryptographically-secure random generator and for strong probable primes (generation and testing), you should consider moving to [bigint-crypto-utils](https://github.com/juanelas/bigint-crypto-utils)
_The operations supported on BigInts are not constant time. BigInt can be therefore **[unsuitable for use in cryptography](https://www.chosenplaintext.ca/articles/beginners-guide-constant-time-cryptography.html).** Many platforms provide native support for cryptography, such as [Web Cryptography API](https://w3c.github.io/webcrypto/) or [Node.js Crypto](https://nodejs.org/dist/latest/docs/api/crypto.html)._
## Installation
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`:
```bash
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 minimised version of the [IIFE file](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/dist/bigint-mod-arith-latest.browser.min.js) or the [ES6 module](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/dist/bigint-mod-arith-latest.browser.mod.min.js) from GitHub.
## Usage example
With node js:
```javascript
const bigintModArith = require('bigint-mod-arith');
/* Stage 3 BigInts with value 666 can be declared as BigInt('666')
or the shorter new no-so-linter-friendly syntax 666n.
Notice that you can also pass a number, e.g. BigInt(666), but it is not
recommended since values over 2**53 - 1 won't be safe but no warning will
be raised.
*/
let a = BigInt('5');
let b = BigInt('2');
let n = BigInt('19');
console.log(bigintCryptoUtils.modPow(a, b, n)); // prints 6
console.log(bigintCryptoUtils.modInv(BigInt('2'), BigInt('5'))); // prints 3
console.log(bigintCryptoUtils.modInv(BigInt('3'), BigInt('5'))); // prints 2
```
From a browser, you can just load the module in a html page as:
```html
<script type="module">
import * as bigintModArith from 'bigint-mod-arith-latest.browser.mod.min.js';
let a = BigInt('5');
let b = BigInt('2');
let n = BigInt('19');
console.log(bigintModArith.modPow(a, b, n)); // prints 6
console.log(bigintModArith.modInv(BigInt('2'), BigInt('5'))); // prints 3
console.log(bigintModArith.modInv(BigInt('3'), BigInt('5'))); // prints 2
</script>

For web browsers, you can also directly download the [IIFE bundle](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/lib/index.browser.bundle.js) or the [ES6 bundle module](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/lib/index.browser.bundle.mod.js) from GitHub.
## Usage example
With node js:
```javascript
const bigintModArith = require('bigint-mod-arith');
Import your module as :
- Node.js
```javascript
const bigintCryptoUtils = require('bigint-mod-arith')
... // your code here
```
- JavaScript native project
```javascript
import * as bigintCryptoUtils from 'bigint-mod-arith'
... // your code here
```
- Javascript native browser ES6 mod
```html
<script type="module">
import * as bigintCryptoUtils from 'lib/index.browser.bundle.mod.js' // Use you actual path to the broser mod bundle
... // your code here
</script>
import as bcu from 'bigint-mod-arith'
... // your code here
```
- JavaScript native browser IIFE
```html
<script src="../../lib/index.browser.bundle.js"></script>
<script>
... // your code here
</script>
- TypeScript
```typescript
import * as bigintCryptoUtils from 'bigint-mod-arith'
... // your code here
```
> BigInt is [ES-2020](https://tc39.es/ecma262/#sec-bigint-objects). In order to use it with TypeScript you should set `lib` (and probably also `target` and `module`) to `esnext` in `tsconfig.json`.
```javascript
/* Stage 3 BigInts with value 666 can be declared as BigInt('666')
or the shorter new no-so-linter-friendly syntax 666n.
Notice that you can also pass a number, e.g. BigInt(666), but it is not
recommended since values over 2**53 - 1 won't be safe but no warning will
be raised.
*/
let a = BigInt('5');
let b = BigInt('2');
let n = BigInt('19');
const a = BigInt('5')
const b = BigInt('2')
const n = BigInt('19')
console.log(bigintCryptoUtils.modPow(a, b, n)); // prints 6
console.log(bigintCryptoUtils.modPow(a, b, n)) // prints 6
console.log(bigintCryptoUtils.modInv(BigInt('2'), BigInt('5'))); // prints 3
console.log(bigintCryptoUtils.modInv(BigInt('2'), BigInt('5'))) // prints 3
console.log(bigintCryptoUtils.modInv(BigInt('3'), BigInt('5'))) // prints 2
console.log(bigintCryptoUtils.modInv(BigInt('3'), BigInt('5'))); // prints 2
```
From a browser, you can just load the module in a html page as:

# bigint-mod-arith
Some extra functions to work with modular arithmetic using native JS ([ES-2020](https://tc39.es/ecma262/#sec-bigint-objects)) implementation of BigInt. It can be used by any [Web Browser or webview supporting BigInt](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt#Browser_compatibility) and with Node.js (>=10.4.0).
> The operations supported on BigInts are not constant time. BigInt can be therefore **[unsuitable for use in cryptography](https://www.chosenplaintext.ca/articles/beginners-guide-constant-time-cryptography.html).** Many platforms provide native support for cryptography, such as [Web Cryptography API](https://w3c.github.io/webcrypto/) or [Node.js Crypto](https://nodejs.org/dist/latest/docs/api/crypto.html).
## Installation
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`:
```bash
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.js) or the [ES6 bundle module](https://raw.githubusercontent.com/juanelas/bigint-mod-arith/master/lib/index.browser.bundle.mod.js) from GitHub.
## Usage example
Import your module as :
- Node.js
```javascript
const bigintCryptoUtils = require('bigint-mod-arith')
... // your code here
```
- JavaScript native project
```javascript
import * as bigintCryptoUtils from 'bigint-mod-arith'
... // your code here
```
- Javascript native browser ES6 mod
```html
<script type="module">
import * as bigintCryptoUtils from 'lib/index.browser.bundle.mod.js' // Use you actual path to the broser mod bundle
... // your code here
</script>
import as bcu from 'bigint-mod-arith'
... // your code here
```
- JavaScript native browser IIFE
```html
<script src="../../lib/index.browser.bundle.js"></script>
<script>
... // your code here
</script>
- TypeScript
```typescript
import * as bigintCryptoUtils from 'bigint-mod-arith'
... // your code here
```
> BigInt is [ES-2020](https://tc39.es/ecma262/#sec-bigint-objects). In order to use it with TypeScript you should set `lib` (and probably also `target` and `module`) to `esnext` in `tsconfig.json`.
```javascript
/* Stage 3 BigInts with value 666 can be declared as BigInt('666')
or the shorter new no-so-linter-friendly syntax 666n.
Notice that you can also pass a number, e.g. BigInt(666), but it is not
recommended since values over 2**53 - 1 won't be safe but no warning will
be raised.
*/
const a = BigInt('5')
const b = BigInt('2')
const n = BigInt('19')
console.log(bigintCryptoUtils.modPow(a, b, n)) // prints 6
console.log(bigintCryptoUtils.modInv(BigInt('2'), BigInt('5'))) // prints 3
console.log(bigintCryptoUtils.modInv(BigInt('3'), BigInt('5'))) // prints 2
```
