Get / Set JSON Value?

I’m having some issues when attempting to set and get a JSON value, currently I have some code similar to the following:

      memcache.get(username, function(err, value, key) {
        var query, siteCode, user, userCredentials;
        if (err != null) {
          winston.error("BasicAuth: Error occured when attempting to search memcache for the user, error follows: " + (util.inspect(err)));
          return done(err);
        }
        if (value != null) {
          user = value.toJSON();
          if (passwordHash.verify(password, user.hashedPassword)) {
            winston.info("BasicAuth: User " + username + " with siteCode " + siteCode + " successfully logged in");
            return done(null, user);
          } else {
            return done(null, false, {
              message: 'Invalid username/password combination'
            });
          }
        }
        memcache.set(username, { some: 'JSON value', with: 'A Few', arrays: [] }, function(err, success) {
          if (err != null) {
            winston.error("BasicAuth: Failed to store the users details in memcache, error follows: " + (util.inspect(err)));
            return done(null, userDetails);
          }
          winston.info("BasicAuth: Successfully stored user's details in the memcache server");
          winston.info("BasicAuth: User " + username + " with siteCode " + siteCode + " successfully logged in");
          return done(null, {});
        })
      }

But when I call the get and then user = value.toJSON(); I get a zero length array!?

I’ve written a simple wrapper that handles this nicely:

memjs = require('memjs')

class SimpleCache
    constructor: () ->
        @cache = memjs.Client.create(null, {expires: 24 * 60 * 60})

    get: (key, callback) ->
        @cache.get key, (err, value) ->
            return callback(err) if err
            value = value.toString()
            try
                value = JSON.parse(value)
            catch e
                null
            callback(null, value)

    set: (key, value, callback) ->
        @cache.set key, JSON.stringify(value), callback

    del: (keys, callback) ->
        @cache.del keys, callback

module.exports = new SimpleCache()

@alevy I got there in the end, I realised that I needed to call JSON.stringify when setting and then JSON.parse(buffer.toString()) when getting the data. But I agree, an example would have been nice! 👍
