Application Development

This page describes different aspects of developing and running your Molybden application.

Running application

Once you generated a Molybden project and installed dependencies, you can run your application by executing the following command in the project root directory:

npm run molybden dev

This command will run the application in development mode.

Development mode

In the development mode, Molybden starts a local development server that will serve the application frontend. The application frontend will be displayed in the application window by navigating to the local development server URL.

It significantly speeds up the development process because you don’t need to rebuild the application frontend every time you change the code. Moreover, the application frontend will be automatically reloaded in the application window when you change the code thanks to the Hot Module Replacement feature.

Developing application backend

The application backend is written in C++. To simplify the development process, Molybden generates a CMakeLists.txt file you can open in your favorite C++ IDE.

It allows you to modify the application backend code using all the features of your IDE such as code completion, syntax highlighting, code navigation, etc.

Once you change the code, you can rebuild and run the application right from your IDE.

Run app in CLion

You can always use the command line to build and run your application:

npm run molybden dev

Adding dependencies

If you need to add a third-party library to your application backend, you can do it by adding the library to the CMakeLists.txt file.

Developing application frontend

To speed up the development process, Molybden allows you to generate a project with a pre-configured frontend framework. But you can develop the application frontend using any of the following approaches:

  • You can use any frontend framework such as React, Vue, Angular, etc.
  • You can use Vanilla JavaScript/TypeScript with HTML and CSS.
  • You can even use a remote URL as the application frontend.

Molybden doesn’t restrict you in any way. Use the approach that suits you best.

Frontend frameworks

The official Molybden scaffolding tool allows generating a project with the most popular frontend frameworks:

The generated project includes everything required to start developing your application frontend with the selected framework. It includes the package.json npm configuration file where all the dependencies and run/build scripts are listed, a sample application frontend that you can use as a reference, and the build tools required to build the application frontend including a local development server with the Hot Module Replacement feature.

Hot Module Replacement

Hot Module Replacement (HMR) is a feature in frontend development that allows developers to update modules in real-time without requiring a full page reload.

With HMR, developers can make changes to their code, such as JavaScript, CSS, or HTML, and see the updates immediately reflected in the application browser window without losing the current application state.

Remote URL as the app frontend

If you just want to display a web page in the application window, then you can simply load the URL as shown below:

#include "molybden.hpp"

using namespace molybden;

void launch() {
  App::init([](std::shared_ptr<App> app) {
    auto browser = Browser::create(app);

Adding dependencies

If you want to use a third-party library in your application frontend, you can do it by adding the library to the package.json file.
