tsconfig tsBuildInfoFile Specify the folder

N/A

💻 Code

After running tsc --init the generated tsconfig.json includes the following line:

  // "tsBuildInfoFile": "./",                          /* Specify the folder for .tsbuildinfo incremental compilation files. */

🙁 Actual behavior

The description says "Specify the folder" and the sample value also indicates that you specify a folder for this option.

However, specifying a folder would result in a following error when running tsc:

error TS5033: Could not write file '/path/to/folder': EISDIR: illegal operation on a directory, open '/path/to/folder'.

🙂 Expected behavior

Actually you need to specify the file .

The official tsConfig doc also says “This setting lets you specify a file”.

A fix would be, for example:

  // "tsBuildInfoFile": "./.tsbuildinfo",                          /* Specify the path to .tsbuildinfo incremental compilation file. */
