## Installation
|
|
### npm
|
|
Install with `npm`:
|
|
|
|
```bash
|
|
npm install katex
|
|
# or globally
|
|
npm install -g katex
|
|
```
|
|
|
|
### Yarn
|
|
Install with `Yarn`:
|
|
|
|
```bash
|
|
yarn add katex
|
|
# or globally
|
|
yarn global add katex
|
|
```
|
|
|
|
### Building from Source
|
|
To build you will need Git, Node.js 8 or later, and Yarn.
|
|
|
|
Clone a copy of the GitHub source repository:
|
|
```bash
|
|
git clone https://github.com/KaTeX/KaTeX.git
|
|
cd KaTeX
|
|
```
|
|
|
|
Then install dependencies and run `build` script:
|
|
```bash
|
|
yarn
|
|
yarn build
|
|
```
|
|
|
|
It will automatically transpile code and include only necessary fonts for
|
|
target environments specified by [Browserslist config](https://github.com/browserslist/browserslist#environment-variables).
|
|
For example, if you are making a web app for a kiosk with Chrome 68, run
|
|
`BROWSERSLIST="Chrome 68" yarn build` and it will produce build with no
|
|
transpilation, as it fully supports ES6, and only include WOFF2 fonts.
|
|
|
|
You can override included fonts using environment variables. Set `USE_(FONT NAME)`
|
|
environment variable to `"true"` or `"false"`, to force a font type to be included
|
|
or excluded, respectively.`
|
|
|
|
If you'd like to use the built KaTeX in other projects, install the package by
|
|
specifying the path:
|
|
```bash
|
|
yarn add /path/to/KaTeX
|
|
# or using npm
|
|
npm install /path/to/KaTeX
|
|
```
|
|
|
|
> You can manually download the package and source code from
|
|
[GitHub releases](https://github.com/KaTeX/KaTeX/releases).
|
|
|
|
## Importing
|
|
KaTeX is exported as a CommonJS module, which can be imported using `require`:
|
|
```js
|
|
const katex = require('katex');
|
|
```
|
|
|
|
If you're using a module loader, transpiler, or bundler that supports interoperability
|
|
between ECMAScript module and CommonJS module, you can use `import`:
|
|
```js
|
|
import katex from 'katex';
|
|
```
|
|
|
|
KaTeX also provides an ECMAScript module:
|
|
```js
|
|
import katex from 'katex/dist/katex.mjs'
|
|
```
|
|
|
|
> The ES module contains ES6 syntaxes and features, and may need transpiling to
|
|
use in old environments:
