Sequelize: Optional limit parameter

Question

I've seen a few questions on optional where clauses and order params, both of which I can implement, but I was wondering how to have an optional limit parameter? Maybe I'm missing something easy, but I can't see anything obvious in the docs

If I specify it like this:

const limit = req.query.limit;
Example.findAll({ 
  limit: limit
})

how can I omit limit in certain situations?

Answer 1

You can simply define findAll options outside findAll call and add limit prop optionally only if you have a value in req.query.limit :

const options = {
}
if (req.query.limit) {
  options.limit = req.query.limit
}
Example.findAll(options)

Or you can try to pass null if you don't ave a value in the req.query.limit (should work in PostgreSQL for instance).
