Dev Docs

The indexPatterns service is now available from the data plugin.

class MyPlugin {
  start(core, data) {
    const indexPatterns = data.indexPatterns.get(indexPatternId);
    ...
  }
}

Type Definitions

• The IIndexPattern type replaces the legacy StaticIndexPattern type
• IndexPattern was moved to the new plugin.
• FieldList was moved to the new plugin and the IFieldList type was added.
• Field was moved to the new plugin, along side the IFieldType type.

    import { IIndexPattern, IFieldType } from 'src/plugins/data/public';
    const indexPattern: IIndexPattern = data.indexPatterns.find(indexPatternId);
    const field: IFieldType[] = indexPattern.fields;

Helper functions

    import { indexPatterns as indexPatternsUtils } from 'src/plugins/data/public';

    const indexPattern: IIndexPattern = indexPatterns.getFromSavedObject(savedObject)
    const isValid = indexPatterns.validateIndexPattern(indexPatternString)

Deletions

• IndexPatternAlreadyExists
• NoDefaultIndexPattern
• NoDefinedIndexPatterns
