## Introduction
A framework for building GraphQL APIs without defining any kind of schema.
It reduces the time spent on writing and maintaining API definitions, allowing you to focus solely on writing your service logic.
## Why
We believe that the current approach to building APIs is outdated. Writing and maintaining API definitions is time-consuming and error-prone. When you already have TypeScript definitions, why not use them to infer the API schema? Pylon does exactly that.
Pylon also provides a set of tools to help you build, test, and deploy your APIs. We believe that building services should be easy and fun. Major functionalities like authentication, authorization, and context management are built-in, so you can focus on what matters most: your service logic.
With Pylon, you can build APIs faster, with fewer errors, and with less code.
## Roadmap
We would love to hear your feedback and suggestions for new features. Please open an issue or join our Discord server to share your thoughts.
- [ ] **Documentation:** Improve the documentation and provide more examples.
- [ ] **Testing:** Add a test suite to ensure the stability of the framework. [#7](https://github.com/getcronit/pylon/issues/7)
- [ ] **Breaking Change Detection:** Implement a mechanism to detect breaking changes in the generated schema. [#8](https://github.com/getcronit/pylon/issues/8)
- [ ] **Date-Based Versioning:** Automatically version the service when backward-incompatible changes are made. This will ensure that clients are aware of the changes and can adapt accordingly. This should be similar to the way Shopify handles API versioning. [#9](https://github.com/getcronit/pylon/issues/9)
- [ ] **GraphQL Directives:** Allow users to define custom directives that can be used to modify the generated schema. These directives should then be applied to the service logic (schema) to provide additional functionality. More information can be found in the [GraphQL spec](https://spec.graphql.org/June2018/#sec-Type-System.Directives).
- [ ] **Support Custom Authentication:** Currently, Pylon only supports OIDC for ZITADEL for authentication. We would like to add support for different authentication methods, such as JWT, OAuth, and others. This will then be used by the ´requireAuth´ function to authenticate / authorize users. [#21](https://github.com/getcronit/pylon/issues/21)
- [ ] **Better Prisma Integration:** Improve the integration with Prisma to provide a more seamless experience when working with databases. This includes better support for relations, pagination, and other features provided by Prisma. The main pain point is that prisma does not include relations by default, so a lot of manual work is required to add them. To solve this, we would like to leverage the prisma client extensions to automatically resolve relations and provide paginatable connections.
- [ ] **Find Edge Cases:** Find edge cases where the generated schema does not match the service logic, or build errors occur. This will help to improve the overall stability of the framework and provide a better developer experience.
- [ ] **Fix the Sentry Integration:** Currently, the Sentry integration is not working as expected. We would like to fix this and provide better error tracking capabilities for Pylon users.
- [ ] **Integrate @getcronit/pylon-builder into @getcronit/pylon-dev:** The pylon-builder package is used to generate the schema from the service logic. Currently, this is a separate package that gets installed alongside the pylon-dev package. This means that there could be version mismatches between the two packages. To solve this, we would like to integrate the builder into the dev package so that they are always in sync. This will also make it easier to maintain and update the packages.
- [ ] **Spread the Word:** Spread the word about Pylon and get more people involved in the project. This includes writing blog posts, creating videos, and sharing the project on social media.
## Create
To create a new Pylon project, run the following command:
```bash
npm create pylon@latest
```
Afterwards, you can navigate to the newly created project and start the development server:
```bash
cd my-pylon
npm run dev
```
This will start the development server on `http://localhost:3000`.
Open the [Pylon Playground](https://pylon.cronit.io/docs/getting-started#built-in-graphql-playground) in your browser and start building your API.
## Develop
Update your service logic in the `src` directory.
```typescript
import {app} from '@getcronit/pylon'
export const graphql = {
Query: {
user: (id: string) => {
return {
id,
name: 'John Doe',
email: '[email protected]'
}
},
products: () => [
{id: '1', name: 'Laptop', price: 999.99},
{id: '2', name: 'Smartphone', price: 499.99},
{id: '3', name: 'Tablet', price: 299.99}
]
},
Mutation: {
updateUserEmail: (id: string, newEmail: string) => {
return {
id,
email: newEmail
}
},
createOrder: (userId: string, productIds: string[]) => {
return {
id: 'order-123',
userId,
productIds,
status: 'PENDING'
}
}
}
}
export default app
```
**Query:**
```graphql
query GetUser {
user(id: "1") {
id
name
email
}
}
query GetProducts {
products {
id
name
price
}
}
```
**Mutation:**
```graphql
mutation UpdateUserEmail {
updateUserEmail(id: "1", newEmail: "[email protected]") {
id
email
}
}
mutation CreateOrder {
createOrder(userId: "1", productIds: ["1", "2"]) {
id
userId
productIds
status
}
}
```
## Deploy
Pylon is fully compatible with Cloudflare Workers, allowing you to deploy your service to the edge in just one minute.
Watch the video below to see how easy it is to deploy a Pylon.
If you prefer to deploy your service to a different platform, you can use the provided Dockerfile to build a Docker image and deploy it to your favorite cloud provider.
```bash
docker build -t my-pylon .
docker run -p 3000:3000 my-pylon
```
## Runtimes
Designed to be flexible, Pylon can be run on various platforms, including:
