The .je-project-settings folder inside your project will contain all your project settings, also about cordova, ionic, etc.

Default setting files of an empty project:

• bookmarks.json: it will contain all your project bookmarks.
• project_details: it will contain all your project details such as the project name, author, etc. The default value is:

{ "project_name": "", "author": "", "author_uri": "", "description": "", "version": "", "license": "", "license_uri": "", "tags": "" } 

• project_settings: here you could define the node.js, npm, yarn, flow and flow-remove-types custom paths and other options for your project. The default value is:

{ "node_js_custom_path": "", "npm_custom_path": "", "yarn_custom_path": "", "use_yarn": false, "build_flow": { "source_folders": [], "destination_folder": "", "options": [], "on_save": true }, "flow_checker_enabled": true, "flow_cli_custom_path": "", "flow_remove_types_custom_path": "", "jsdoc": { "conf_file": "" } } 

All the paths could be absolute or relative to the path project (without considering the .je-project-settings folder!!!). If you want use Yarn, set "use_yarn": true. "conf_file" contains the path of the configuration file for jsdoc. "build_flow" will be used for building the application after clicking Tools > Build Flow. "source_folders" represents a list of files or directories that must be compiled. "destination_folder" represents the destination folder after the compilation. "options" is a list of parameters that will be added to the flow-remove-types command (more info here). "on_save": true means that when you save a javascript file in your project, it will compile the project automatically.
