Discovering all imported dependencies in a TypeScript project: A step-by-step guide

Currently, I am attempting to consolidate external libraries into a vendor bundle through webpack. Instead of manually listing dependencies, I would like to automate this process by scanning all TypeScript files in the directory and generating an array of package imports accordingly.

While searching for a solution, I came across a npm package that performs similar functionality, but it only supports .js files rather than TypeScript: https://www.npmjs.com/package/find-imports.

If anyone has advice or suggestions on how to achieve this for TypeScript files, I would greatly appreciate it.

Answer №1

Not exactly what you're in search of, but have you considered exploring the require.context feature within webpack? This feature enables you to define a directory and a regular expression to compare file names within that directory.

For instance, the code snippet below imports any files that match the pattern /\.ts$/ from the folder 'path/to/folder'. The parameter true signifies that the specified folder will be searched recursively, including its sub-folders.

const myImports = require.context('path/to/folder', true, /\.ts$/);
myImports.keys().forEach(myImports);

Answer №2

Consider utilizing an AST generator tool

// Retrieve all import declarations
const imports = sourceFile.getImportDeclarations();
// Or get the first one with a default import
const importWithDefaultImport = sourceFile.getImportDeclaration(i => i.getDefaultImport() != null);
const someModuleImport = sourceFile.getImportDeclaration("module-specifier-text");

This example is sourced from:

Note: ts-simple-ast has now been rebranded as ts-morph, it is recommended to conduct further research independently.
