Every data management system has at least three basic functions: create, delete, and update. In this video, learn how to create CRUD functions with Mongoose.
- [Instructor] First of all we will require the model…const ItemModel equals require…and from models I take the mongoose ItemModel…that we defined before.…Next, I will simply define an asynchronous function,…async function getAll…and that's quite easy actually…because this function does nothing more…than returning ItemModel.find all,…so we pass in an empty query object…and I want to sort it,…so I add .sort…and in round brackets I add a child script object…that says createdAt: -1.…
This will sort the result in descending order…by creation date.…Here we also have to fix a little bit the indentations…so that eslint is happy.…Next we will implement a function getOne,…so I add async function getOne…and I pass in the itemId…and return ItemModel.findOne,…that's the function provided by Mongoose…and I want to search for or query for _id,…that's the ID of this one record of the document…should be itemId.…
Let's fix here a little bit the blank…so that eslint is happy.…So, we have implemented now getAll and getOne…but we haven't yet really exported anything…
