Entrypoint

class Entrypoint extends ChunkGroup

Entrypoint serves as an encapsulation primitive for chunks that are a part of a single ChunkGroup. They represent all bundles that need to be loaded for a single instance of a page. Multi-page application architectures will typically yield multiple Entrypoint objects inside of the compilation, whereas a Single Page App may only contain one with many lazy-loaded chunks.

new Entrypoint(): Entrypoint

entrypoint.getModuleIndex(module): number | undefined

entrypoint.getModuleIndex2(module): number | undefined

Returns the configured name of the chunk group, if one was assigned. Updates the configured name of the chunk group.

Exposes the group's async dependency blocks as an iterable.

Returns a debug-only identifier derived from the group's member chunk debug ids. This is primarily useful in diagnostics and assertions.

Returns an identifier derived from the ids of the chunks currently in the group.

entrypoint.addAsyncEntrypoint(entrypoint): boolean

Registers an async entrypoint that is rooted in this chunk group.

entrypoint.addBlock(block): boolean

Associates an async dependency block with this chunk group.

entrypoint.addChild(group): boolean

Adds a child chunk group to the current group.

entrypoint.addDependOn(entrypoint): void

entrypoint.addOptions(options): void

Merges additional options into the chunk group. Order-based options are combined by taking the higher priority, while unsupported conflicts surface as an explicit error.

entrypoint.addOrigin(module, loc, request): void

Records where this chunk group originated from in user code. The origin is used for diagnostics, ordering, and reporting.

entrypoint.addParent(parentChunk): boolean

Records a parent chunk group relationship.

entrypoint.checkConstraints(): void

entrypoint.compareTo(chunkGraph, otherGroup): -1 | 0 | 1

Sorting predicate which allows current ChunkGroup to be compared against another. Sorting values are based off of number of chunks in ChunkGroup.

entrypoint.dependOn(entrypoint): boolean

entrypoint.getBlocks(): AsyncDependenciesBlock[]

Returns the async dependency blocks that create or reference this group.

entrypoint.getChildOrderOptions(childGroup, chunkGraph): Record<string, number>

Aggregates per-block *Order options for the blocks that bridge this chunk group to the given child chunk group. *Order options are tied to the originating import() call and must not be sourced from the child's shared options, otherwise a webpackPrefetch/Preload directive from one parent would leak into other parents that share the child by name.

entrypoint.getChildren(): ChunkGroup[]

Returns the child chunk groups reachable from this group.

entrypoint.getChildrenByOrders(moduleGraph, chunkGraph): Record<string, ChunkGroup[]>

Groups child chunk groups by their *Order options and sorts each group by descending order and deterministic chunk-group comparison.

entrypoint.getEntrypointChunk(): Chunk

Returns the chunk which contains the entrypoint modules (or at least the execution of them)

entrypoint.getFiles(): string[]

Collects the emitted files produced by every chunk in the group.

entrypoint.getModulePostOrderIndex(module): number | undefined

Returns the module's bottom-up traversal index within this group.

entrypoint.getModulePreOrderIndex(module): number | undefined

Returns the module's top-down traversal index within this group.

entrypoint.getNumberOfBlocks(): number

entrypoint.getNumberOfChildren(): number

entrypoint.getNumberOfParents(): number

entrypoint.getParents(): ChunkGroup[]

Returns the parent chunk groups that can lead to this group.

entrypoint.getRuntimeChunk(): Chunk | null

Fetches the chunk reference containing the webpack bootstrap code

entrypoint.hasBlock(block): boolean

Checks whether an async dependency block is associated with this group.

entrypoint.hasParent(parent): boolean

Checks whether the provided group is registered as a parent.

entrypoint.insertChunk(chunk, before): boolean

Inserts a chunk directly before another chunk that already belongs to the group, preserving the rest of the ordering.

entrypoint.isInitial(): boolean

Indicates whether this chunk group is loaded as part of the initial page load instead of being created lazily.

entrypoint.pushChunk(chunk): boolean

Appends a chunk to the group when it is not already a member.

entrypoint.remove(): void

Disconnects this group from its parents, children, and chunks. Child groups are reconnected to this group's parents so the surrounding graph remains intact after removal.

entrypoint.removeChild(group): boolean

Removes a child chunk group and clears the corresponding parent link on the removed child.

entrypoint.removeChunk(chunk): boolean

Removes a chunk from this group.

entrypoint.removeParent(chunkGroup): boolean

Removes a parent chunk group and clears the reverse child relationship.

entrypoint.replaceChunk(oldChunk, newChunk): boolean | undefined

Replaces one member chunk with another while preserving the group's ordering and avoiding duplicates.

entrypoint.setEntrypointChunk(chunk): void

Sets the chunk with the entrypoint modules for an entrypoint.

entrypoint.setModulePostOrderIndex(module, index): void

Stores the module's bottom-up traversal index within this group.

entrypoint.setModulePreOrderIndex(module, index): void

Stores the module's top-down traversal index within this group.

entrypoint.setRuntimeChunk(chunk): void

Sets the runtimeChunk for an entrypoint.

entrypoint.sortItems(): void

entrypoint.unshiftChunk(chunk): boolean

Moves a chunk to the front of the group or inserts it when it is not already present.
