Question

Getting exported members through Typescript Compiler API can be achieved by following these steps:

I am currently working on a project hosted at https://github.com/GooGee/Code-Builder

This particular file is being loaded by the Typescript Compiler API:


import * as fs from 'fs'

Below is a snippet of my code:


function getExportList(node: ts.Identifier, checker: ts.TypeChecker) {
    const symbol = checker.getSymbolAtLocation(node)
    return checker.getExportsOfModule(symbol)
}

I am attempting to retrieve exported members of the module fs.

I am aware that the symbol is not a ts.ModuleSymbol, which means it will not work as intended.

What steps should I take next?

Answer №1

To obtain the aliased symbol from the local fs symbol in your possession, follow these steps:

const localFsSymbol = typeChecker.getSymbolAtLocation(node)!; // remember to handle cases where it is undefined
const fsSymbol = typeChecker.getAliasedSymbol(localFsSymbol);
const moduleExports = typeChecker.getExportsOfModule(fsSymbol);

// The output will be an array of exported names like ["rename", "renameSync", "truncate", ...etc...]
console.log(moduleExports.map(s => s.name));

If this method does not yield results, check for any diagnostics present in the program:

const diagnostics = ts.getPreEmitDiagnostics(program);
console.log(diagnostics);
