| 16 | ## Installation
|
| 17 |
|
| 18 | * **I'm using Node.js, Webpack, Browserify, Rollup, or another module bundler,
|
| 19 | and install packages from npm.**
|
| 20 | * First, install the `simple-statistics` module, using `npm install simple-statistics`,
|
| 21 | then include the code with require or import:
|
| 22 | * **I use the `require` function to use modules in my project. (most likely)**
|
| 23 | * When you use `require`, you have the freedom to assign the module to any
|
| 24 | variable name you want, but you need to specify the module's name exactly:
|
| 25 | in this case, 'simple-statistics'. The `require` method returns an object
|
| 26 | with all of the module's methods attached to it.<br /> <pre>var ss = require('simple-statistics')</pre>
|
| 27 | * **I use `import` to use modules in my project. I'm probably using Babel, `@std/esm`, Webpack, or Rollup.**
|
| 28 | * Import all functions under the ss object: <pre>import * as ss from 'simple-statistics'</pre>
|
| 29 | Include a specific named export: <pre>import {min} from 'simple-statistics'</pre>
|
| 30 | Simple statistics has _only_ named exports for ES6.
|
| 31 | * **I'm using Deno.**
|
| 32 | * Simple Statistics is published for Deno: https://deno.land/x/simplestatistics
|
| 33 | * **I'm not using a module bundler. I'm writing a web page, and want to include
|
| 34 | simple-statistics using a script tag.**
|
| 35 | * **I want to support all browsers**
|
| 36 | * When you use simple-statistics from a script tag, you don't get to choose
|
| 37 | the variable name it is assigned to: simple-statistics will always become
|
| 38 | available globally as the variable `ss`. You can reassign this variable to
|
| 39 | another name if you want to, but doing so is optional.
|
| 40 | ```HTML
|
| 41 | <script src='https://unpkg.com/simple-statistics@7.7.6/dist/simple-statistics.min.js'>
|
| 42 | </script>
|
| 43 | ```
|
| 44 | * **I want to use ES6 modules in a browser and I'm [willing to only support new browsers](https://caniuse.com/#feat=es6-module) to do it**
|
| 45 | * This module works great with the [`?module`](https://unpkg.com/#/query-parameters) query parameter of unpkg. If you
|
| 46 | specify `type='module'` in your script tag, you'll be able to import simple-statistics
|
| 47 | directly - through `index.js` and with true [ES6 import syntax and behavior](http://exploringjs.com/es6/ch_modules.html).
|
| 48 | ```js
|
| 49 | <script type='module'>
|
| 50 | import {min} from "https://unpkg.com/simple-statistics@7.7.6/index.js?module"
|
| 51 | console.log(min([1, 2, 3]))
|
| 52 | </script>
|
| 53 | ```
|
| 54 | This feature is still experimental in unpkg and very bleeding-edge.
