Part dependencies

Dependencies in a part’s configuration object are controlled by the from and after properties.

NOTE

In both cases, you should specify the actual configuration object of the dependency part, not merely a string with its name.

TIP

Dependencies configured on parts do not need to be included in the parts property passed to the Design constructor. FreeSewing core will recursively resolve all dependencies and add them to the design for you.

after

The after property holds an array of parts that should be drafted before the current part:

Javascript
import { exampleBack } from './back.mjs'
import { exampleFront } from './front.mjs'

const part = {
  name: 'example.sleeve',
  after: [ exampleBack, exampleFront ],
  draft: ({ part }
) => part
}

The effect of the after property is that drafting of this part will be deferred until all the parts listed in the after property are drafted.

TIP

If you only have one part for the after property, you do not have to specify an array:

Javascript
import { exampleBack } from './back.mjs'

const part = {
  name: 'example.front',
  after: exampleBack,
  draft: ({ part }
) => part
}

from

The from property holds a part that should be used as the base for the current part. In other words, the current part will extend the part listed in front and inherit all its content.

Javascript
import { exampleBack } from './back.mjs'

const part = {
  name: 'example.front',
  from: exampleBack,
  draft: ({ part }
) => part
}
WARNING

Unlike after, from only ever takes one part since you can only extend one part.
