Before you start
Download and install Node.js.
Install JSCS globally
In the embedded Terminal (⌥F12) , type:
npm install jscs -g
Enable JSCS and configure its behavior in AppCode
In the Preferences dialog ⌃⌥S, go to . On the JSCS page, that opens, select the Enable checkbox. After that the other controls on the page become available.
In the Node Interpreter field, specify the path to Node.js. If you followed the standard installation procedure, AppCode detects the path and fills in the field itself.
In the JSCS Package field, specify the location of the
jscspackage installed in the current project.
Specify the configuration to use.
By default, AppCode first looks for a
jscsConfigproperty in the package.json file of the current project. If no such property is found, AppCode looks for a .jscsrc or a .jscs.json configuration file. AppCode starts the search from the folder where the file to be checked is stored, then searches in the parent folder, and so on until reaches the project root. Accordingly, you have to define the configuration to apply either as a
jscsConfigproperty in the package.json file or in a .jscsrc or a .jscs.json configuration file, or in a custom JSON configuration file.
You can also apply a predefined set of rules, either independently or in combination with a configuration file. In the latter case, the rules from the configuration file override the predefined rules.
To have AppCode look for a
jscsConfigproperty in the package.json file or for a .jscsrc or a .jscs.json file, choose the Search for config(s) option.
To use a custom file, choose the Configuration File option and specify the location of the file in the Path field. Select the path from the list, or type it manually, or click and select the relevant file from the dialog that opens.
To have a predefined set or rules applied, choose the desired set from the Code Style Preset list.
If necessary, from the Code Style Preset list, select the set of predefined rules associated with the code style you use.
