The central window of Zettlr using the Night Theme


Zettlr is an electron-based app, so to start developing, you'll need to have a NodeJS-stack on your computer installed. Make sure node and preferably Yarn are installed, which is the recommended package manager.

Then, simply clone the repository and install the dependencies on your local computer:

$ git clone https://github.com/Zettlr/Zettlr.git
$ cd Zettlr
$ yarn install # Or npm install
$ cd source
$ yarn install # Or npm install

(Please note the second yarn install/npm install in the source directory. This is necessary to build the app locally.)

There are four types of templates shipped with the app that need a rebuild once you change them: The stylesheets, which are written in LESS, the HTML templates, written in Handlebars.js, and some components, written in Vue.js. Additionally, the template for the reveal.js-presentations needs to be built prior to running the app. Whenever you make changes to any of these resources, you'll need to recompile them using an appropriate command:

$ yarn less # Or npm run less, this recompiles the stylesheets
$ yarn handlebars # Or npm run handlebars, this recompiles the templates
$ yarn wp:dev # Or npm run wp:dev, this recompiles the Vue components
$ yarn reveal:build # Or npm run reveal:build, needs to be run once
