Vite 3: defining a global variable in the config adds a newline at the end of the string-CodePudding

Vite 3 gives us the option to

As you can see, there is a newline at the end of the string. This is unwanted and causes errors with tracking (it causes a mismatch on release versions).

It's also visible in the minified files:

Is there any way to mitigate this, or should I find another way to access this variable?

CodePudding user response：

In your getReleaseVersion, you are using the the full output of running the command. This includes the trailing newline output by Git*.

To get the string you want, you will need to strip that trailing newline. For example:

const commitHash = childProcess
    .execSync('git rev-parse --short HEAD')
    .toString()
    .trim(); // This "removes the leading and trailing whitespace and line terminator characters from a string."

The reason the trim you are already doing does not work is that it is operating on the JSON-encoded string, so the first and last characters are double quotes and all newlines are escaped (e.g., ' foo\n' -> '" foo\\n"'). Thus, it does nothing.

* Almost all CLI programs output a trailing newline so that the terminal prompt is on a new line to the output.
