Technology is a spiral, with foundational ideas resurfacing. Java revolutionized enterprise applications. REST and JSON simplified building APIs and websites. Node.js enabled fast and custom development, leading to the microservices revolution. Platformatic aims to fill the gap in building, managing, and scaling microservices painlessly.

As developers we stand on the shoulders of giants, and it can be helpful to take a look at the past to gain a better perspective. In this talk we’ll briefly explore the past decade of backend development and architectural patterns. We’ve often ditched technologies in an attempt to make the developer experience frictionless. However we sometimes forget what we can learn from “the good old days”. What are you building: a monolith, a microservices system or something in between? A shift in how we see things can help us keep moving forwards.

APIs are Evolving. Again.

The Talk discusses the use of TypeScript and SQL together in software development. It explores different approaches, such as using an ORM like TypeORM or a schema generator like pg2ts. Query builders like connects JS and tools like PGTyped are also discussed. The benefits and trade-offs of using TypeScript and SQL are highlighted, emphasizing the importance of finding a middle ground approach.

We all love writing types in TypeScript, but we often find ourselves having to write types in another language as well: SQL. This talk will present the choose-your-own-adventure story that you face when combining TypeScript and SQL and will walk you through the tradeoffs between the various options. Combined poorly, TypeScript and SQL can be duplicative and a source of headaches, but done well they can complement one another by addressing each other's weaknesses.

Building a scalable GraphQL server can be challenging. There are multiple reasons to build a GraphQL server, such as optimizing client requests and wrapping microservices. The SDL first GraphQL server allows you to write your schema separately from your resolvers, giving you full control. You can create a GraphQL API automatically from a schema, simplifying the process and eliminating the need for manual deployments. The schema can link data sources and third-party APIs, allowing for easy integration and customization.

Every (frontend) developer is asking for a GraphQL API but often lacks the backend knowledge to create a performant server. There are many different flavors in creating the perfect GraphQL server, ranging from schema-first to code-first or even auto generated solutions. Let me show you the pros and cons of each solution so, after this talk, you'll know which solution would best fit your team. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Alex introduces tRPC, a toolkit for making end-to-end type-safe APIs easily, with auto-completion of API endpoints and inferred data from backend to frontend. tRPC works the same way in React Native and can be adopted incrementally. The example showcases backend communication with a database using queries and validators, with types inferred to the frontend and data retrieval done using Prisma ORM.

Why are we devs so obsessed with decoupling things that are coupled nature? tRPC is a library that replaces the need for GraphQL or REST for internal APIs. When using it, you simply write backend functions whose input and output shapes are instantly inferred in your frontend without any code generation; making writing API schemas a thing of the past. It's lightweight, not tied to React, HTTP-cacheable, and can be incrementally adopted. In this talk, I'll give a glimpse of the DX you can get from tRPC and how (and why) to get started.
