string-replace

Asynchronous version of String.prototype.replace.

Example

stringReplace('name: {name}, value: {value}', /\{([^}]+)\}/g, replace,
              function done(err, result) {
  if (err) throw err;
  console.log(result);
});

function replace(cb, match, key) {
  // Do some async stuff here.
  // Arguments to this function are almost the same as for String.prototype.replace.
  // Except for the callback.
  // ...
  cb(null, value);
}

API

stringReplace(string, pattern, replacer(cb, match, ...), [opts], cb(err, result))

Applies String.prototype.replace asynchronously.

Replaces all occurences of pattern (regexp or string) in a string with invocations of replacer function. Functionally equivalent to string.replace(pattern, replacer(match, ...)) but replacer has to return value by calling cb.

Replacers are firing in sequence unless opts.parallel is set to true.
