Welcome to this introductory guide on leveraging tRPC for full-stack development. With TypeScript's increasing popularity, tRPC has surfaced as a modern standard that empowers developers to achieve automatic type safety, an optimized developer experience, and exceptional compatibility with existing JavaScript frameworks. This guide aims to introduce you on integrating tRPC into your web stack and its efficient usage with PostgreSQL's modern features and TailwindCSS. This educational article is specifically designed for individuals who:

Serving a web application to a global audience requires deploying, hosting and scaling it on reliable cloud infrastructure. Heroku is a cloud platform as a service (PaaS) that supports many server-side languages (e.g., Node.js, Go, Ruby and Python), monitors application status in a beautiful, customizable dashboard and maintaining an add-ons ecosystem for integrating tools/services such as databases, schedulers, search engines, document/image/video processors, etc. Although it is built on AWS, Heroku is simpler to use compared to AWS. Heroku automatically provisions resources and configures low-level infrastructure so developers can focus exclusively on their application without the additional headache of manually setting up each piece of hardware and installing an operating system, runtime environment, etc. When deploying to Heroku, Heroku's build system packages the application's source code and dependencies together with a language runtime using a buildpack and slug compiler to generate a slug , which is a highly optimized and compressed version of your application. Heroku loads the slug onto a lightweight container called a dyno . Depending on your application's resource demands, it can be scaled horizontally across multiple concurrent dynos. These dynos run on a shared host, but the dynos responsible for running your application are isolated from dynos running other applications. Initially, your application will run on a single web dyno, which serves your application to the world. If a single web dyno cannot sufficiently handle incoming traffic, then you can always add more web dynos. For requests exceeding 500ms to complete, such as uploading media content, consider delegating this expensive work as a background job to a worker dyno. Worker dynos process these jobs from a job queue and run asynchronously to web dynos to free up the resources of those web dynos.

From businesses looking to optimize their operations, data influences the decisions being made. For scientists looking to validate their hypotheses, data influences the conclusions being arrived at. Regardless, the sheer amount of data collected and harnessed from various sources presents the challenge of identifying rising trends and interesting patterns hidden within this data. If the data is stored within an SQL database, such as PostgreSQL , querying data with the expressive power of the SQL language unlocks the data's underlying value. Creating interfaces to fully leverage the constructs of SQL in analytics dashboards can be difficult if done from scratch. With a library like React Query Builder , which contains a query builder component for fetching and exploring rows of data with the exact same query and filter rules provided by the SQL language, we can develop flexible, customizable interfaces for users to easily access data from their databases. Although there are open source, administrative tools like pgAdmin , these tools cannot be integrated directly into a custom analytics dashboard (unless embedded within an iframe). Additionally, you would need to manage more user credentials and permissions, and these tools may be considered too overwhelming or technical for users who aren't concerned with advanced features, such as a procedural language debugger, and intricate back-end and database configurations. By default, the <QueryBuilder /> component from the React Query Builder library contains a minimal set of controls only for querying data with pre-defined rules. Once the requested data is queried, this data can then be summarized by rendering it within a data visualization, such as a table or a line graph.
