astHelpers.createNamespaceImport() function

Adds a namespace import to a script AST. If an import declaration for the module already exists, this function merges the namespace specifier into that declaration. It doesn't create duplicate imports.

Signature:

export declare function createNamespaceImport(ast: namedTypes.Program, moduleSpecifier: string, namespaceName: string): void;

Parameters

Parameter	Type	Description
ast	namedTypes.Program	The script AST.
moduleSpecifier	string	The module name to import from, such as 'lodash-es'.
namespaceName	string	The local name for the namespace import.

Returns:

void

Exceptions

An error if the declaration already has a namespace import under a different name.

Example

// import * as _ from 'lodash-es';
createNamespaceImport(scriptAST, 'lodash-es', '_');
