Idea is a very popular integrated development environment that provides many convenient functions and tools to help developers improve work efficiency. One of them is the ability to set up JavaScript-related environments and configurations for better front-end development. In this article, we will introduce how to set up Idea's JavaScript environment and related configurations.

Step one: Install JavaScript plug-in

Before using Idea for JavaScript development, we need to install the corresponding plug-in first. In Idea, we can find and install plug-ins through the Plugin Manager. Open the plug-in manager, enter the "JavaScript" keyword to search, find the JavaScript plug-in that suits us, and install it.

Step 2: Configure the JavaScript running environment

After installing the JavaScript plug-in, we need to configure the JavaScript running environment. In Idea, we can configure it through the following steps:

1. Open the "File" menu and select the "Settings" option.
2. In the pop-up dialog box, select the “Languages ​​& Frameworks” option and expand the “JavaScript” option.
3. In the "JavaScript" option, find the "Node.js interpreter" option, click the "..." button, and select the Node.js interpreter installed locally.
4. In the “JavaScript” option, find the “Language version” option and select the JavaScript version that suits us.
5. If you need to check and format the JavaScript code style, you can find the "Code Quality" option in the "JavaScript" option and configure it accordingly.

Step 3: Configure JavaScript related tools

When developing JavaScript, we may need to use corresponding tools and frameworks, such as React, Vue, Angular, etc. In Idea, we can integrate these tools through plug-ins or the dependency management of the project itself.

1. Plug-in management method: Find the plug-in suitable for us, install it and configure it accordingly.
2. The project's own dependency management method: Just add the corresponding dependencies and configurations in the project's package.json file.

Step 4: Configure JavaScript debugger

When developing JavaScript, we may encounter various problems. At this time, we need to use the debugger to debug the code. Perform debugging. In Idea, we can configure the JavaScript debugger through the following steps:

1. Open the JavaScript file that needs to be debugged.
2. On the left side of the code line, click in a blank space to add a breakpoint before the code line.
3. Click the “Run” menu and select the “Edit Configurations…” option.
4. In the pop-up dialog box, select the “JavaScript Debug” option and configure the corresponding parameters.
5. Click the "OK" button to save the configuration.
6. Click the "Run" menu and select the "Debug..." option to start the debugger.
7. Debug the code, find problems and solve them.

Summary:

In this article, we introduced how to set up Idea’s JavaScript environment and related configurations. We need to complete the following steps: install JavaScript plug-ins, configure the JavaScript runtime environment, configure JavaScript-related tools, and configure the JavaScript debugger for better JavaScript development. I hope this article can help you develop JavaScript smoothly and improve work efficiency.
