The singleton service lifetime is most appropriate because BooksService takes a direct dependency on MongoClient. In the preceding code, the BooksService class is registered with DI to support constructor injection in consuming classes. This technique provides access to the appsettings.json configuration values that were added in the Add a configuration model section. In the preceding code, a BookStoreDatabaseSettings instance is retrieved from DI via constructor injection. Public async Task RemoveAsync(string id) =>Īwait _booksCollection.DeleteOneAsync(x => x.Id = id) Public async Task UpdateAsync(string id, Book updatedBook) =>Īwait _booksCollection.ReplaceOneAsync(x => x.Id = id, updatedBook) Public async Task CreateAsync(Book newBook) =>Īwait _booksCollection.InsertOneAsync(newBook) _booksCollection = mongoDatabase.GetCollection(ī) Īwait _booksCollection.Find(_ => true).ToListAsync() Īwait _booksCollection.Find(x => x.Id = id).FirstOrDefaultAsync() Var mongoDatabase = mongoClient.GetDatabase(ī) Private readonly IMongoCollection _booksCollection ī) For example, the BookStoreDatabaseSettings object's ConnectionString property is populated with the BookStoreDatabase:ConnectionString property in appsettings.json.Īdd the following code to the top of Program.cs to resolve the BookStoreDatabaseSettings reference: using BookStoreApi.Models Īdd a Services directory to the project root.Īdd a BooksService class to the Services directory with the following code: using BookStoreApi.Models In the preceding code, the configuration instance to which the appsettings.json file's BookStoreDatabase section binds is registered in the Dependency Injection (DI) container. The JSON and C# property names are named identically to ease the mapping process.Īdd the following highlighted code to Program.cs: var builder = WebApplication.CreateBuilder(args) ī("BookStoreDatabase")) The preceding BookStoreDatabaseSettings class is used to store the appsettings.json file's BookStoreDatabase property values. The following result is displayed: = null! If the database does exist, its connection is opened for transactions.Ĭreate a Books collection using following command: db.createCollection('Books') ![]() Run the following command in the command shell: use BookStoreĪ database named BookStore is created if it doesn't already exist. In the command shell connect to the default test database by running the following command: mongosh Open a MongoDB command shell instance by launching mongosh.exe. For more information on MongoDB Shell commands, see mongosh. Use the previously installed MongoDB Shell in the following steps to create a database, make collections, and store documents. Replace with the directory chosen in the previous step. In the OS command shell (not the MongoDB Shell), use the following command to connect to MongoDB on default port 27017. The mongo Shell doesn't create new directories. Create the directory if it doesn't exist. Add the resulting path for mongosh.exe to the PATH environment variable.Ĭhoose a directory on the development machine for storing the data. Add C:\Program Files\MongoDB\Server\\bin to the PATH environment variable.ĭownload the MongoDB Shell and choose a directory to extract it to.
