Possibility to change the key after you have initialised the rate limiter about node-rate-limiter-flexible

@aaron-russell Here is an example (I omit some code, which you already have)

const opts = {
  points: 6,
  duration: 1,
  storeClient: sequelize,
  tableName: 'RateLimit',
};

const rateLimiterUsernamelookup = new RateLimiterPostgres({...opts, keyPrefix: 'UsernameLookup'}, ready);

const rateLimiterPasswordReset = new RateLimiterPostgres({...opts, keyPrefix: 'PasswordReset'}, ready);

exports.rateLimiting = (req, res, next) => {
  let rateLimiter = null
  if (req.path.indexOf('username') > -1 {
    rateLimiter = rateLimiterUsernamelookup
  } else  if (req.path.indexOf('passwordReset') > -1 {
    rateLimiter = rateLimiterPasswordReset
  }
  if (rateLimiter !== null) {
      rateLimiter.consume(req.ip, 1)
        .then((rateLimiterRes) => {
          next();
        })
        .catch(() => {
          res.status(429).send('Too Many Requests');
        });
  } else {
    next()
};

Don't know why I didn't think of that. Thank you!

@aaron-russell Hi.
There is keyPrefix option. It allows to store data for different limiters in the same table.
You can create 2 limiters with different keyPrefix and consume points from appropriate limiter depending on conditions.

Hi @animir
But that would require a lot of duplicate code because it would the the exact same filw, just with the keyPrefix changed? Or am I missing something?
