redis caching with mongodb

isCached

To check if an key is cached in redis you write the following

isCached(key, callback);

cache

To cache data you run the following function

cache(
  key,
  document,
  settings,
  callback
);

Settigns could be the following

{
  forceUpdate: true,
  duration: -1
}

forceUpdate set to true overwrites the data if already cached duration is how long the key should be active, -1 is infinite

uncache

To uncache data the following function is called

unCache(
  key,
  settings,
  callback
);

Settings could be the following

{
  forceDel:  true,
  duration: 10
}

forceDel deletes the key without taking duration into account duration sets a duration for when it should delete

MongoDB manipulation

set data

To set data you run the following function

  setData(
    key,
    document,
    data,
    settings,
    callback
  );

settings can be

{
    cache: true,
    duration: 100,
    forceUpdate: false
}

cache is whether the data should be cached duration and forceUpdate is only taking into consideration if cache is true duration is how long the key should be cached forceUpdate overwrites any old cache with the same key

get data

to get data you run

getData(
  key,
  document,
  settings,
  callback
);

settings can be

{
    cache: true,
    duration: 100,
    forceUpdate: false
}

cache is whether the data should be cached duration and forceUpdate is only taking into consideration if cache is true duration is how long the key should be cached forceUpdate overwrites any old cache with the same key

update data

to update data run

updateData(
  key,
  doc,
  query,
  data,
  settings
);

settings take

{
    cache: true,
    duration: 100,
    forceUpdate: false
}

cache is whether the data should be cached duration and forceUpdate is only taking into consideration if cache is true duration is how long the key should be cached forceUpdate overwrites any old cache with the same key

query is written in the following way

{
  key: key,
  // Any know data
}

delete data

delete data with

deleteData(
  key,
  document,
  query,
  settings,
  callback
);

settings take

{
    keepCached: true,
    duration: 100,
}

keepCached is if the data being removed should be stored duration is how long the key should be cached. Can't be -1 as it should be deleted
