Installation and Startup Process

Installation

yarn nocobase init

• app.constructor()
• app.parse()
  • yarn nocobase init
    Initialize the installation
    • app.load()
      Load the configuration
      • app.exitAsync('beforeLoad')
        Hook before all configurations are loaded
      • app.pluginManager.load()
        Load the configurations of all active plugins in order
        • Load the configuration of plugin-collections
        • Add app.on('init') listener
          • db.getModel('collections').load()
            Import the collections table configuration into db.table()
          • app.db.sync({force: false})
            Execute sync again to create the data table configured in the collections table
      • app.exitAsync('afterLoad')
        All hooks after the configuration is loaded
      • app.db.sync({force: true})
        Generate data tables, fields, indexes, etc. according to the configuration
      • app.emitAsync('init')
        Perform all init listeners, generally initialized data operations
        • trigger the init event of plugin-collections and the data table is created
      • app.stop()
        End

Startup

yarn nocobase start --init --sync
# --init for quick installation at startup
# --sync to quickly build or update tables when app.collection() is updated in the development environment

• app.constructor()
• app.parse()
  • yarn nocobase start
    Initialize the installation
    • app.load()
      Load the configuration
      • app.exitAsync('beforeLoad')
        Hook before all configurations are loaded
      • app.pluginManager.load() Load the configurations of all active plugins in order
        • Load the configuration of plugin-collections
          • Add app.on('start') listener
          • db.getModel('collections').load()
            Import the collections table configuration into db.table(), no need for db.sync in the start process
      • app.exitAsync('afterLoad')
        All hooks after configuration loading
      • app.db.sync({force: false})
        yarn nocobase start --sync to quickly build or update tables when there are updates
        yarn nocobase start --init quick init
      • app.emitAsync('init')
        yarn nocobase start --init shortcut init
      • app.exitAsync('start')
        Execute all start listeners, usually reading some necessary data from the data table
      • app.listen() Start the http server
