Quickstart

In this quickstart guide, you'll learn the typical workflow with Teo from creating an empty project, setting up a connection with a local database to sending HTTP requests with the generated query client.

Choose your stack

Before getting started, pick and select your own technical stack. And this guide will just be tailored for you. Also, your preferences are saved locally. The next time you open any documentation in our site, your tech stack preferences are preserved and restored for you.

Prerequisites

1. Create a new project and set up Teo

2. Connect to database and set up server

Create a file at project root directory named schema.teo with the following content:

Within this connector config block, we specified the database to connect. Next, let's declare a server block to specify the port that this HTTP server should be listening on. We specified the port value 5050. Our server will be listening on port 5050 after started.

server {
  bind: ("0.0.0.0", 5050)
}
 
request middlewares [logRequest]

Look at the request middlewares thing. There is a middleware in the standard library called logRequest. It will log each incoming requests to the console.

3. Model your data in the schema

Now time for modeling data. Let's dive right in to declare some models.

Models in the Teo schema have two main purposes:

• Represent the tables or collections in the underlying database
• Represent a group of API resource including handler actions like findMany, findUnique, create, etc.

4. Generate query client

If you start the server with cargo teo serve, you can already see server started and listening on the desired port. Instead of writing each HTTP request on the frontend, Teo can generate a client for you with great auto completion.

Add this block into schema.teo:

Now let's run this command to generate a brand new client.

5. Send HTTP requests with query client

Start a development server with this command:

Now navigate to the generated client and write some code to perform HTTP requests.

cd ../hello-teo-client

6. Next steps

In this Quickstart guide, you have a brief overview and understand how Teo works. To learn further, read our Beginner tutorial. Feel free to explore the server & clients API a bit more on your own, e.g. by including filtering, sorting, and pagination options in the findMany requests or exploring more operations like update and delete objects.
