)

func (ImportKind) IsFromCSS added in v0.7.8

func (kind ImportKind) IsFromCSS() bool

func (ImportKind) StringForMetafile added in v0.8.32

type ImportRecord added in v0.5.4

type ImportRecord struct {
	Assertions *[]AssertEntry
	Path       logger.Path
	Range      logger.Range

	// The resolved source index for an internal import (within the bundle) or
	// nil for an external import (not included in the bundle)
	SourceIndex Index32

	Flags ImportRecordFlags
	Kind  ImportKind
}

type ImportRecordFlags added in v0.14.7

type ImportRecordFlags uint16
const (
	// Sometimes the parser creates an import record and decides it isn't needed.
	// For example, TypeScript code may have import statements that later turn
	// out to be type-only imports after analyzing the whole file.
	IsUnused ImportRecordFlags = 1 << iota

	// If this is true, the import contains syntax like "* as ns". This is used
	// to determine whether modules that have no exports need to be wrapped in a
	// CommonJS wrapper or not.
	ContainsImportStar

	// If this is true, the import contains an import for the alias "default",
	// either via the "import x from" or "import {default as x} from" syntax.
	ContainsDefaultAlias

	// If this is true, the import contains an import for the alias "__esModule",
	// via the "import {__esModule} from" syntax.
	ContainsESModuleAlias

	// If true, this "export * from 'path'" statement is evaluated at run-time by
	// calling the "__reExport()" helper function
	CallsRunTimeReExportFn

	// Tell the printer to wrap this call to "require()" in "__toESM(...)"
	WrapWithToESM

	// Tell the printer to wrap this ESM exports object in "__toCJS(...)"
	WrapWithToCJS

	// Tell the printer to use the runtime "__require()" instead of "require()"
	CallRuntimeRequire

	// True for the following cases:
	//
	//   try { require('x') } catch { handle }

	//   try { require.resolve('x') } catch { handle }
	//   import('x').catch(handle)
	//   import('x').then(_, handle)
	//
	// In these cases we shouldn't generate an error if the path could not be
	// resolved.
	HandlesImportErrors

	// If true, this was originally written as a bare "import 'file'" statement
	WasOriginallyBareImport

	// If true, this import can be removed if it's unused
	IsExternalWithoutSideEffects
)

func (ImportRecordFlags) Has added in v0.14.7

func (flags ImportRecordFlags) Has(flag ImportRecordFlags) bool

type Index32 added in v0.8.50

type Index32 struct {
	// contains filtered or unexported fields
}

This stores a 32-bit index where the zero value is an invalid index. This is a better alternative to storing the index as a pointer since that has the same properties but takes up more space and costs an extra pointer traversal.

func MakeIndex32 added in v0.8.50

func MakeIndex32(index uint32) Index32

func (Index32) GetIndex added in v0.8.50

func (i Index32) GetIndex() uint32

func (Index32) IsValid added in v0.8.50

func (i Index32) IsValid() bool
