uiModifications (preview)

To consume the UI Modifications (UIM) API, your app needs to import the @forge/jira-bridge package:

1
2
import { uiModificationsApi } from '@forge/jira-bridge';

This API is strictly related to the Jira UI modifications module

Initialization

onInit method signature

1
2
onInit(<initCallback>, <registerFieldsCallback>): void

onInit method description

initCallback is where apps can query field data and request modifications. registerFieldsCallback is used to specify which fields will be changed by initCallback. The information returned by registerFieldsCallback is used to display a loading indicator next to the relevant fields until initCallback finishes.

Both callback functions are called every time:

• the GIC form is opened
• the project or issueType (from context) changes
• an issue is created with the "create another issue" checkbox enabled

The initCallback function will receive one object as an argument. This object contains the following attributes:

• api - the API used to find and modify the GIC fields
• uiModifications - an array of UIM entities registered for a given context

The registerFieldsCallback function will receive an object containing:

• uiModifications - an array of UIM entities registered for a given context

1
2
uiModificationsApi.onInit(({ api, uiModifications }) => {
  // You can find form fields using the FieldQueryingAPI here
  const summaryField = api.getFieldById('summary');
  // You can manipulate the fields you found
  if (summaryField) {
    summaryField.setDescription('New summary description');
  }
}, ({ uiModifications }) => {
  // This function should return an array of the IDs of the fields
  // which are going to be changed in initCallback
  return ['summary'];
})

All modifications requested synchronously using this API will be batched and applied at once.

If a Promise is returned from the callback, all of the modifications will be postponed until the Promise resolves. This may be useful in a scenario when the app needs to perform an async operation before it requests a change.

Reacting to change

onChange method signature

1
2
onChange(<changeCallback>, <registerFieldsCallback>): void

onChange method description

changeCallback is where apps can query field data and request modifications. registerFieldsCallback is used to specify which fields will be changed by changeCallback. The information returned by registerFieldsCallback is used to display a loading indicator next to the relevant fields until changeCallback finishes.

Both callback functions are called every time:

• the blur form field event is triggered by one of the GIC-supported text fields, which are summary and description
• the change form field event is triggered by any other GIC-supported field

The changeCallback function will receive one object as an argument. This object contains the following attributes:

• api - the API used to find and modify the GIC fields
• change - an object with the current attribute containing the object exposing the FieldAPI of the field which triggered the change event
• uiModifications - an array of UIM entities registered for a given context

The registerFieldsCallback function will receive an object containing:

• change - an object with the current attribute containing the object exposing the FieldAPI of the field which triggered the change event
• uiModifications - an array of UIM entities registered for a given context

uiModificationsApi.onChange(({ api, change, uiModifications }) => {
  // You can find form fields using the FieldQueryingAPI here
  // You can also manipulate the fields you found or access the field
  // that triggered the change
  const { current } = change;
  if (current.getId() === 'summary') {
    // hint: You may want to read the content of uiModifications before
    // deciding what changes need to be applied here
    current.setDescription('New summary description');
  }
}, ({ change, uiModifications }) => {
  // This function should return an array of the IDs of the fields
  // which are going to be changed in changeCallback
  return ['summary'];
})

All modifications requested synchronously using this API will be batched and applied at once.

If a Promise is returned from the callback, all of the modifications will be postponed until the Promise resolves. This may be useful in a scenario when the app needs to perform an async operation before it requests a change.

Querying fields

getFieldById method signature

1
2
getFieldById(<fieldId>): FieldAPI | undefined

getFieldById method description

Accepts one argument: fieldId (string) - the ID of the field which the app wants to work on.

Returns the FieldAPI object if the field exists on the GIC form.

Returns undefined if the field doesn't exist on the GIC form.

1
2
uiModificationsApi.onInit(({ api }) => {
  const { getFieldById } = api;
  const description = getFieldById('description')
  // You can perform operations on 'description'
  // field using the FieldAPI here
}, () => ['description'])

Common FieldAPI

getId

1
2
getId(): string

Returns the field's ID.

setName

1

setName(value: string): FieldAPI

Changes the field's name.

Example:

1
2
field.setName('New name for the field');

getName

1
2
getName(): string

Returns the field's name.

setDescription

1
2
setDescription(value: string): FieldAPI

Changes the field's description.

Example:

1
2
field.setDescription('This the description!');

getDescription

1
2
getDescription(): string

Returns the field’s description.

setVisible

1
2
setVisible(value: boolean): FieldAPI

Changes field visibility. The form payload will contain the field’s value, but the field won’t be visible in the UI if this is set to false.

Example:

1
2
field.setVisible(false);

isVisible

1
2
isVisible(): boolean

Returns true if the field is currently visible. Returns false otherwise.

setValue

setValue(value: unknown): FieldAPI

Set a given field's value. See the specific field value contracts in the supported fields below to make sure the changes requested by this method will be applied.

getValue

1
2
getValue(): unknown

Set a given field's value. See the specific field value contracts in the supported fields below to make sure the changes requested by this method will be applied.
