![]() ![]() Now our database is completely in sync with our Prisma schema, there is another command that we need to run, this one is for TypeScript it will create the types using the Prisma schema so that your application will be completely type-safe.įor that run npx prisma generate this will generate the TypeScript defenitions inside the folder. If you encounter errors when running this command, make sure that Postgres is installed properly on your computer and the username and password that you put inside the. The migrations will be put into the folder prisma/migrations In the root directory of your application run npx prisma migrate dev this will make the changes to your database and migrate the changes. Now that we have defined our schemas, it’s time to make these changes in the Postgres database as well, because this schema is nothing but a piece of code, we’ll have to tell Prisma to take these schemas and make these changes in the database as well.įor that Prisma has provided us with a command. We just need to add two more lines of code in the schema. Now that we defined both collections for the users and the games, it’s now time to define the relationships between them.Īs mentioned before, we want a user to be able to have multiple games, and we also don’t want duplicate game entries so we want a game to be associated with multiple users as well. Games on the other hand can be connected to multiple users as well. What you’ll have to change is just the database name, username, and password of your Postgres database when you first installed it, if you want to create a new user, here is how.īefore building our REST API let’s first build the schemas for our database collections, we’ll have two collections, users and games for this tutorial.Įach user can have multiple games, so there are database relations involved as well. env file that Prisma already created for you. ![]() In order to change your database URL, you’ll have to change it from the. Install the Prisma and Prisma client by running yarn add -D prisma and yarn add your datasource db configurations, make sure you choose postgresql as your database. Initialize a node.js application by running npm init Once you get into the directory run npx prisma init this will create a folder named “prisma” with some basic configurations. Contributions are welcome via the Remult GitHub repository.First create a folder and cd into it, for example, mkdir prisma & cd prisma Remult is open-source software available under the MIT license. This example demonstrates the ease and flexibility with which Remult can be incorporated into the front end of an application, allowing developers to seamlessly leverage the power and functionality of Remult across the entire stack. import from "./shared/Contact"Ĭonst contactsRepo = remult.repo(Contact)Ĭonst = useState() Using decorators, Remult simplifies the process of creating entities and their associated fields, making it more efficient and intuitive for developers. Developers can accomplish this easily by adding the Entity decorator to the class and applying the relevant field decorators to each property. Remult utilizes decorators to transform basic JavaScript classes into Remult Entities. Remult solves this problem by providing an integrated model that defines the database schema, exposes simple CRUD APIs, and supports client-side integration that enables developers to query the database, all while maintaining type safety easily. However, maintaining separate sets of models and validators can result in redundancy, increased maintenance overhead, and the potential for errors when the models become out of sync. Server models specify the structure of the database and API, while client models define the data transmitted to and from the API. ![]() In software development, two data models must be managed and synchronized to ensure proper system functionality: server and client models. Remult is a full-stack CRUD library that simplifies development by leveraging TypeScript models, providing a type-safe API client and query builder. ![]()
