interface Engine

interface Engine<

SchematicMetadataT is a type that contains additional typing for the Schematic Description.

Type Aliases

type Action

type Action =
    | CreateFileAction
    | OverwriteFileAction
    | RenameFileAction
    | DeleteFileAction;

type AsyncFileOperator

type AsyncFileOperator = (tree: FileEntry) => Observable<FileEntry | null>;

type CollectionDescription

type CollectionDescription<CollectionMetadataT extends object> =
    CollectionMetadataT & {
        readonly name: string;
        readonly extends?: string[];
    };

The description (metadata) of a collection. This type contains every information the engine needs to run. The CollectionMetadataT type parameter contains additional metadata that you want to store while remaining type-safe.

type DryRunEvent

type DryRunEvent =
    | DryRunErrorEvent
    | DryRunDeleteEvent
    | DryRunCreateEvent
    | DryRunUpdateEvent
    | DryRunRenameEvent;

type FileOperator

type FileOperator = (entry: FileEntry) => FileEntry | null;

A FileOperator applies changes synchronously to a FileEntry. An async operator returns asynchronously. We separate them so that the type system can catch early errors.

type FileVisitor

type FileVisitor = FilePredicate<void>;

type PathTemplateData

type PathTemplateData = {
    [key: string]: PathTemplateValue | PathTemplateData | PathTemplatePipeFunction;
};

type PathTemplatePipeFunction

type RuleFactory

type RuleFactory<T extends object> = (options: T) => Rule;

A rule factory, which is normally the way schematics are implemented. Returned by the tooling after loading a schematic description.

type SchematicContext

type SchematicContext = TypedSchematicContext<{}, {}>;

This is used by the Schematics implementations in order to avoid needing to have typing from the tooling. Schematics are not specific to a tool.

type SchematicDescription

type SchematicDescription<
    CollectionMetadataT extends object,
    SchematicMetadataT extends object
> = SchematicMetadataT & {
    readonly collection: CollectionDescription<CollectionMetadataT>;
    readonly name: string;
    readonly private?: boolean;
    readonly hidden?: boolean;
};

The description (metadata) of a schematic. This type contains every information the engine needs to run. The SchematicMetadataT and CollectionMetadataT type parameters contain additional metadata that you want to store while remaining type-safe.

type Source

type Source = (context: SchematicContext) => Tree | Observable<Tree>;

A source is a function that generates a Tree from a specific context. A rule transforms a tree into another tree from a specific context. In both cases, an Observable can be returned if the source or the rule are asynchronous. Only the last Tree generated in the observable will be used though.
We obfuscate the context of Source and Rule because the schematic implementation should not know which types is the schematic or collection metadata, as they are both tooling specific.

type TaskExecutor

type TaskExecutor<T = {}> = (
    options: T | undefined,
    context: SchematicContext
) => Promise<void> | Observable<void>;

type Tree

type Tree = TreeInterface;

class BaseWorkflow

abstract class BaseWorkflow implements Workflow {}

Base class for workflows. Even without abstract methods, this class should not be used without surrounding some initialization for the registry and host. This class only adds life cycle and dryrun/force support. You need to provide any registry and task executors that you need to support. See implementation for how to make a specialized subclass of this. TODO: add default set of CoreSchemaRegistry transforms. Once the job refactor is done, use that as the support for tasks.
