Create a projectContribute

Create with your favorite language

Once the Lenra client is downloaded, you can set your preferred language to start your application with by downloading a template.

Create a new lenra project

To create a new lenra project you can just run the lenra new command. This command takes two parameters:

• The template name
• The project name

lenra new javascript my-app
cd my-app

{:.info.lenra-icon-info} All the guides in this documentation will focus on the JavaScript template. Other languages work about the same and main principles remain the same too. Don't be afraid to follow these guides using another language !

Directory structure

First of all, we can see that this project is already versioned with git. This is a usually a good idea to commit your changes early on. This new project is a simple app that showcases a simple counter app.

About the different files :

• package.json Add your project dependency in this file like any other node project are the listeners of this project. A listener is a piece of code that will be executed when a specific action occurs. More on this later.
• services/*.js are modules that take care of sending API calls to Lenra. This will be helpful to create/update/delete data from the database.
• views/*.js are the UI parts of the application. These views can be combined to create complex UI.
• resources/*.js are the images and other resources you need to access from the UI.
• index.js is the manifest where you will register your views and listeners, create your routes etc..
• server.js is the webserver that will take care of the interactions with the lenra back-end. Do not update this file if you don’t know what you are doing !
• lenra.yml is a file that explains to the lenra CLI how to build your app. If you create a complex app that needs other steps to be built and/or started, you will need to edit this file.
