Univer Docs API

Univer Docs provides professional document typesetting capabilities, with concepts closely aligned with Microsoft Word.

Importing

TypeScript
import '@univerjs/docs/facade'import '@univerjs/docs-ui/facade'

Operate Documents

For document units, unitId corresponds to the unique identifier of the document, and documents do not have a subUnitId.

The text content of the document is stored in the body.dataStream string, which does not contain style information.

Style information is stored separately in another data structure and is associated with the text content through index references.

For elements such as line breaks, page breaks, sections, paragraphs, and tables, different special characters are used to mark them in the text content. These special characters are converted to corresponding elements during rendering.

Create Document

Use univerAPI.createDocument(data) to create a new document and get its FDocument facade wrapper.

The parameter is an optional document data object that contains the initial data for the document. If {} is passed, an empty document is created.

When working with the underlying univer instance directly instead of the Facade API, use univer.createUnit(UniverInstanceType.UNIVER_DOC, data).

TypeScript
const doc = univerAPI.createDocument(data)

Get Document unitId

TypeScript
const doc = univerAPI.getActiveDocument()const unitId = doc?.getId()

Get Document Data

TypeScript
const doc = univerAPI.getActiveDocument()const saveData = doc.save()

Dispose Document

When we no longer need the document, we can call the dispose method of the Univer instance to destroy the instance.

TypeScript
univer.dispose()

Operate Text

Modify text elements in the rich text area

Insert Text

To append specified text to the end of this text area.

TypeScript
const doc = univerAPI.getActiveDocument()doc?.insertText(0, 'Univer')

Delete Text

Delete text by document offsets.

TypeScript
const doc = univerAPI.getActiveDocument()doc?.deleteRange({ startOffset: 0, endOffset: 1 })

Modify Style

Set text style on a paragraph.

TypeScript
const doc = univerAPI.getActiveDocument()const paragraph = doc?.getParagraphs()[0]paragraph?.setStyle({  textStyle: {    cl: {      rgb: '#FF0000',    },  },})

Insert Page Break

The \f character is a page break, used to insert a page break in the document.

TypeScript
const doc = univerAPI.getActiveDocument()doc?.insertText(0, '\f')

Document statistics

Use the underlying DocumentDataModel to calculate statistics for the whole document or selected ranges.

TypeScript
const doc = univerAPI.getActiveDocument()if (!doc) throw new Error('No active document')const statistics = await doc.getDocumentDataModel().getStatistics({  locale: univerAPI.Enum.LocaleType.EN_US,})console.log(statistics.words, statistics.charactersWithSpaces, statistics.paragraphs)

getStatistics() returns word, character, and paragraph counts. Pass ranges to count selected text or an AbortSignal in signal to cancel obsolete calculations.
