The startup mechanism runs the installed startup modules at the end of the [[boot process|BootMechanism]].
! Startup Modules
Modules with their ''module-type'' field set to `startup`:
* Must expose a `startup` function
** For synchronous startup modules the startup function is called as `startup()`, asynchronous modules are passed a callback they must invoke on completion: `startup(callback)`
* May expose a `name` property that is used to identify the task
* May expose a `platforms` property containing an array of names of platforms that are required in order for the startup module to be executed. The defined platforms are ''node'' and ''browser''
The startup mechanism begins by sequentially executing the tasks that have no dependencies. It then continues executing tasks as they are unlocked by the completion of their dependencies.
There is no guarantee of the execution order of tasks that share the same dependencies.
! Startup Tasks
The core defines the following sequence of named startup tasks:
