Teo has its own schema language. Models and interfaces are described clearly with this schema language. To write custom code with Teo, we need to transform these Teo schema into developer's handy programming language. Teo generator is a builtin tool to generate programming files.

The generators fall into two main categories:

  • Model entities are used for backend programming
  • Query clients are for simplifying frontend interaction with Teo server

Model entity generator

Model entity generator generates model entities and interfaces directly into the project in which the schema files live. These entity files provide ORM apis and interfaces for writing custom backend server app.

Declare a model entity generator in schema is deadly simple.

entity {
  provider: .rust,
  dest: "./src/entities"

In this example, a Rust entity generator is declared. Use the generate entity command to generate the files into the directory defined with dest key.

Teo model entities behave just like classes and objects in other ORM frameworks. Developers can findMany objects, update, save or delete an object. Transactions are supported with the teo.transaction call.

The generated interfaces are for custom handlers. Developers can fetch data from HTTP request body with type-safe guards and auto-completion.

Query client generator

While model entity generator is for backend. The query client generator is for the frontend. Frontend developers don't need to declare interfaces and DAOs anymore. Let Teo do this boring and redundant job.

Declare a query client generator in schema is deadly simple, too.

client ts {
  provider:  .typeScript,
  dest:      "../hello-teo-client",
  host:      "",
  package:   true,
  gitCommit: true

Run generate client to have a query client generated. Teo query client is type-safe and performant.

Admin dashboard generator

The admin dashboard generator generates an admin dashboard for the project. It reduces a lot of work for hooking things up between the frontend and the backend. The admin dashboard is a running frontend, too. It's written with React and TypeScript. It utilizes TypeScript query client.

Declare an admin dashboard generator in schema is deadly simple, too.

admin {
  dest: "../hello-teo-admin-dashboard",
  host: .inject("process.env.TEO_HOST"),
  languages: [.enUs, .enUk, .de, .es, .fr, .he, .hi, .ja, .ko, .zhCn, .zhTw]

To generate the admin dashboard, use teo generate admin command.

The admin dashboard looks like this:
