Front End Web Development Techdegree Graduate 84,738 PointsWe installed sequelize with npm install sequelize
. So npm fetched the sequelize code and put it in the node_modules
folder. Then under /models
there's an index.js file where we import the sequelize
npm package, create an instance, do some configuration, and at the bottom of the file we end up assigning an object called sequelize
to the exports.
So when you do require('../models').sequelize
, it's going to look in ../models/index.js
because that's the default behavior when you don't specify a file name. And it's going to get that sequelize
object from the exports that was configured.
