As a general rule, you should consider both the features provided and the "community activity" downloads, contributions, bug reports, quality of documentation, etc.
For the Local Library example and the rest of this topic we're going to use the Mongoose ODM to access our library data. This ODM and database combination is extremely popular in the Node community, partially because the document storage and query system looks very much like JSON, and is hence familiar to JavaScript developers. Note: You don't need to know MongoDB in order to use Mongoose, although parts of the Mongoose documentation are easier to use and understand if you are already familiar with MongoDB. The rest of this tutorial shows how to define and access the Mongoose schema and models for the LocalLibrary website example.
Before you jump in and start coding the models, it's worth taking a few minutes to think about what data we need to store and the relationships between the different objects. We know that we need to store information about books title, summary, author, genre, ISBN and that we might have multiple copies available with globally unique ids, availability statuses, etc. We might need to store more information about the author than just their name, and there might be multiple authors with the same or similar names. We want to be able to sort information based on the book title, author, genre, and category.
When designing your models it makes sense to have separate models for every "object" a group of related information. In this case some obvious candidates for these models are books, book instances, and authors. You might also want to use models to represent selection-list options e. A good example is a genre e. Once we've decided on our models and fields, we need to think about the relationships between them. With that in mind, the UML association diagram below shows the models we'll define in this case as boxes. As discussed above, we've created models for the book the generic details of the book , book instance status of specific physical copies of the book available in the system , and author. We have also decided to have a model for the genre so that values can be created dynamically.
We've decided not to have a model for the BookInstance:status — we will hard code the acceptable values because we don't expect these to change. Within each of the boxes, you can see the model name, the field names and types, and also the methods and their return types. The diagram also shows the relationships between the models, including their multiplicities. The multiplicities are the numbers on the diagram showing the numbers maximum and minimum of each model that may be present in the relationship. For example, the connecting line between the boxes shows that Book and a Genre are related.
The numbers close to the Book model show that a Genre must have zero or more Book s as many as you like , while the numbers on the other end of the line next to the Genre show that a book can have zero or more associated Genre s. This choice was somewhat arbitrary — we could equally well have had the field in the other schema. Note: The next section provides a basic primer explaining how models are defined and used. As you read it, consider how we will construct each of the models in the diagram above. This section provides an overview of how to connect Mongoose to a MongoDB database, how to define a schema and a model, and how to make basic queries. Note: This primer is heavily influenced by the Mongoose quick start on npm and the official documentation.
Mongoose is installed in your project package. To install it, use the following command inside your project folder:. If you want to install a MongoDB server then you can download installers from here for various operating systems and install it locally. You can also use cloud-based MongoDB instances. Note: For this tutorial, we'll be using the MongoDB Atlas cloud-based database as a service free tier to provide the database. This is suitable for development and makes sense for the tutorial because it makes "installation" operating system independent database-as-a-service is also one approach you might use for your production database. Mongoose requires a connection to a MongoDB database. You can require and connect to a locally hosted database with mongoose. You can get the default Connection object with mongoose.
Once connected, the open event is fired on the Connection instance. Note: If you need to create additional connections you can use mongoose.
I this tutorial you will learn how to download files from your NodeJS server from your express js application. Express providing Helper function called res. Using this function you can easily allow file downloads from your application. This function, transfers the file at path as an "attachment". Typically, browsers will prompt the user for download. Override this default with the filename parameter. When an error occurs or transfer is complete, the method calls the optional callback function fn. This method uses res. sendFile to transfer the file. Step 2: create a file called index. js of project.
And create a express server with route, it should accept file name in the URL. Step 3: Run the application by issuing node index.
