# 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
|

|

├── LICENSE

└── 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>
|
||||
```

|
||||
|
||||
## 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
|
||||
```
|
||||

|
||||
</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.

# 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
|
||||
|
||||
```
