开启tsconfig.json的traceResolution选项后，输出内容的位置在哪里？

Hey there! Let's tackle your two questions about TypeScript's module resolution tracing feature step by step:

1. How to find the output of traceResolution? #

You can access the trace output in a couple of straightforward ways, depending on how you enable the option:

• Command line direct enable: Run the TypeScript compiler with the flag explicitly:

  tsc --traceResolution
  

  The full module resolution log will print directly to your terminal/console window immediately.
• Via tsconfig.json: If you've already set "traceResolution": true in your tsconfig.json's compilerOptions, just run the standard compile command:

  tsc
  

  The trace log will automatically appear in your terminal alongside any regular compile output.
• Build tools integration: If you're using tools like Webpack, Vite, or ts-node, check the tool's output panel or terminal. Most tools pipe the TypeScript compiler's trace output through to their own logging streams, so you'll find it there.

2. Where does the output go after enabling traceResolution in tsconfig.json? #

By default, the trace resolution logs are sent to standard output (stdout)—meaning they'll show up directly in the terminal window where you run your TypeScript compile command (tsc).

If you want to save the log to a file instead of just viewing it in the terminal, you can use shell redirection to capture the output:

tsc > resolution-trace.log 2>&1

This command saves both the standard output and any error messages into a file named resolution-trace.log in your current working directory.

As per the official definition:

Report module resolution log messages.
