Volt.DepGraph (Volt v0.9.1)

ETS-backed module dependency graph.

Tracks which files import which specifiers, enabling reverse lookups for HMR propagation — "what depends on this file?"

Summary

Functions

clear()

Clear the entire graph.

create_table()

Create the dependency graph ETS table. Called once from Application.start/2.

dependents(specifier)

Find all files that import the given specifier.

dependents_matching(predicate)

Find all files that import a specifier matching the given predicate.

imports_of(path)

Get the imports for a file path.

remove(path)

Remove a file from the graph.

update(path, imports)

Update the imports for a file path.

Functions

clear()

@spec clear() :: :ok

Clear the entire graph.

create_table()

@spec create_table() :: :ok

Create the dependency graph ETS table. Called once from Application.start/2.

dependents(specifier)

@spec dependents(String.t()) :: [String.t()]

Find all files that import the given specifier.

Used by HMR to propagate changes upward through the dependency tree.

dependents_matching(predicate)

@spec dependents_matching((String.t() -> boolean())) :: [String.t()]

Find all files that import a specifier matching the given predicate.

The predicate receives each import specifier and should return true if it matches the file being searched for.

imports_of(path)

@spec imports_of(String.t()) :: [String.t()]

Get the imports for a file path.

remove(path)

@spec remove(String.t()) :: :ok

Remove a file from the graph.

update(path, imports)

@spec update(String.t(), [String.t()]) :: :ok

Update the imports for a file path.
