Download and install Node.js. The framework is required for two reasons:
- The transpiledLanguage toolType is started through Node.js.
- NPM, which is a part of the framework, is also the easiest way to download the transpiledLanguage toolType.
For details on using Node.js in WebStorm, see the section Node.js
If you are going to use the command line mode, make sure the following paths are added to the PATH variable:
- The path to the parent folder of the Node.js executable file.
- The path to the npm folder.
This enables you to launch the transpiledLanguage toolType and npm from any folder.
- Make sure the Mocha test framework is installed as described in Preparing to Use Mocha Test Framework.
- Make sure the Node.js plugin is enabled. The plugin is bundled with WebStorm and activated by default. If it is not, enable it as described in Enabling and Disabling Plugins.
- Make sure the Mocha plugin is enabled. The plugin is bundled with WebStorm and activated by default. If it is not, enable it as described in Enabling and Disabling Plugins.
