Installing JsThemis #

JsThemis is available on npm and can be installed with the usual npm install. Additionally, Themis Core library has to be installed in your system as well.

Themis Core is available as a system package for Linux and macOS. Usually you want to install the stable package to benefit from automatic dependency management and security updates. However, you can also build and install the latest JsThemis from the source code.

Installing stable version on Linux #

The easiest way to install Themis on Linux is to use package repositories for your system. We build packages for a multitude of Linux distributions.

Add Cossack Labs package repositories to your system.
Install Themis Core development package.

For Debian, Ubuntu:
```
sudo apt install libthemis-dev
```
For CentOS, RHEL:
```
sudo yum install libthemis-devel
```
Install JsThemis via npm for your project:
```

```

Once JsThemis is installed, you can try out code examples.
