  findImportingTsFiles,
} from "ts-file-util";

getElementList

The getElementList function retrieves a list of all functions within a TypeScript source file, along with their child functions.

import { getElementList } from "ts-file-util";

// Assume `sourceFile` is a ts.SourceFile instance
const functionList = getElementList(sourceFile);

getFunctionText

The getFunctionText function retrieves the text of a specified function from a TypeScript source file.

import { getFunctionText } from "ts-file-util";

// Assume `sourceFile` is a ts.SourceFile instance
const functionText = getFunctionText("functionName", sourceFile);

findImports

The findImports function retrieves a list of all imported modules in a TypeScript source file.

import { findImports } from "ts-file-util";

// Assume `sourceFile` is a ts.SourceFile instance
const imports = findImports(sourceFile);

findImportedByTsFiles

The findImportedByTsFiles function retrieves a list of all TypeScript files that import a specified file.

import { findImportedByTsFiles } from "ts-file-util";

const importingFiles = findImportedByTsFiles("targetFilePath");

findImportingTsFiles

The findImportingTsFiles function retrieves a list of all TypeScript files that a specified file imports.

import { findImportingTsFiles } from "ts-file-util";

const importedFiles = findImportingTsFiles("filePath");
