Cache with sequelize.query

Question

I would like to know how can I use a cache with Sequelize?

I look at the different package ( sequelize-transparent-cache , ...), but the cache use with the model.

How can I use a cache with sequelize.query('SELECT * FROM Books') and not model?

Answer 1

For example, using Cache-Aside pattern .

The pseudo code is as follows:

async function findAllBooks() {
  let books = await cache.get('books');
  if(!books) {
    books = await sequelize.query('SELECT * FROM Books');
    await cache.set('books', books);
  }
  return books;
}

The sequelize-transparent-cache package uses the same pattern for findByPk() method, see the source code: https://github.com/DanielHreben/sequelize-transparent-cache/blob/master/packages/sequelize-transparent-cache/src/methods/class.js#L14
