Double quote escaping for valid JSON

Question

I have a string say - this is a "string that needs" escaping" . This string ultimately gets saved in a JSON object so the double quotes must be escaped properly.

I've implemented a utility function to escape it -

export function escapeJsonString(str) {
  // eslint-disable-next-line no-useless-escape
  return str.replace(/"/g, '\"');
}

The output form this is exactly what I need - this is a \"string that needs\" escaping . However, eslint complains that the escape character is useless?

Is there a better way to do this while ensuring I am compliant with ESLint? I'd prefer not to turn off this rule.

Answer 1

Well in this case, you can do this.

'this is a \\"string that needs\\" escaping'

ESLint does not complain about this.
