#tc-cache

###Requirement

You have to get a redis bdd running somewhere, as this package will connect to it. You can set cache expiration with the environment variable KL_CACHE_DURATION, which take a duration in seconds.

###Example

Instead of this :

router.get('', async ({query}, res) => {
  try {
    const response = await myService(query);
    res.status(response.status).send(response.body);
  } catch (error) {
    logger.error(error);
    res.status(error.status || 500).send(error);
  }
});

Do this :

const HASH = 'YourHashForThisService';

router.get('', async (req, res) => {
  try {
    const response = await getFromCacheOrHttp(HASH, '/myRoute', req, myService);
    res.status(response.status).send(response.body);
  } catch (error) {
    logger.error(error);
    res.status(error.status || 500).send(error);
  }
});

That's it.
This require to decompose req in your service instead of your route... but let's just say i'm sorry for this.

###Side infos tc-cache also use pino as a logger. You can set it's level by adding an environment variable called LEVEL.
