How to convert JS multi-line string to single-line with tabs-CodePudding

I want to take a string, such as

const code = `
<code>
    This is some code
</code>
`

and convert it automatically to a one line string, using \n for breaks and \t for tabs.

After conversion it should look like:

const code = "\n\tThis is some code\n"

How can this be done in JavaScript? I saw posts solving how to add line breaks, but found nothing for tab support.

CodePudding user response：

one solution could be to find 4 spaces and replace it by \t like this:

const code = `
<code>
    This is some code
</code>
`;
const result = code.replace(/ {4}/g, '\\t').replace(/<\/*code>\n?/g, '').replace(/\n/g, '\\n');
console.log(result);

since OP has said result should be \n\tThis is some code\n, I've also replaced <code></code> with empty string.
