func DepKey ¶

func DepKey(raw string) string

DepKey normalizes a raw npm module string to a lockfile-key form.

"lodash"           -> "lodash"
"lodash/merge"     -> "lodash"
"@scope/pkg"       -> "@scope/pkg"
"@scope/pkg/sub"   -> "@scope/pkg"
"./foo"            -> ""    (relative)
"../foo"           -> ""    (relative)
"/abs/path"        -> ""    (absolute)
"node:fs"          -> ""    (node builtin)
""                 -> ""

Built-in modules (node:fs, node:path, etc.) and bare names that match the historic builtin list (fs, path, http, ...) are NOT stripped here — that's the consumer's job. depusage only refuses the patterns that can never be a registry dep: relative, absolute, and node: scheme.

func Extract ¶

func Extract(body []byte, opts extract.Options) (extract.Result, error)

Extract runs the JS/TS import pass over body.

func IsRelative ¶

func IsRelative(raw string) bool

IsRelative reports whether the raw module string is a relative or absolute filesystem path. Used by the extractor to flag the extract.ImportRelative kind.
