NEWT: Back-end Technology Selection

Choosing the right technology stack

Choosing the right technology stack

Hello! My name is Rodrigo Ramirez, I'm a Full-stack developer at ReiwaTravel, and I had the opportunity and responsibility of selecting NEWT stack. Specially for the Backend and Frontend. Selecting the technology stack, especially for a startup, could be crucial to determine the success of the product and the engineering organization.

NEWT Backend stack

• TypeScript = programming language

• GraphQL = API layer

• GCP = Infra

API Layer

• One way to request information from our Web and Mobile apps.

• The solution should be easy to maintain and scale.

• REST and GraphQL work well in Web and Mobile Apps, but gRPC is not yet well-supported on websites (it may require a proxy)

• Schema-based requests are important to keep a contract between your clients and the server.

• In the case of maintainability and testing, GraphQL and gRPC architecture mainly focus on that, but about REST, you will have to take extra care of the implementation.

• Development Speed & Smaller Payloads were important, and here is where GraphQL and gRPC architecture are ideal for that. REST can cover all the same points, but additional maintenance costs are required. Whereas GraphQL and gRPC offer that out of the box.

Programming Language

• Current team knowledge

• We decided to use GraphQL, so we need a language that fits well with that.

• Easy to Develop and Deploy

• Our team members already had production experience with TypeScript and GraphQL

• Our frontend team also uses Typescript

• Node.JS/Typescript is the most popular option for implementing GraphQL servers.

• Node.JS/Typescript apps can be deployed anywhere.

Infra / Cloud Providers

• We were looking for managed solutions since we didn’t count on a full-time infra engineer.

• It should be easy to deploy, scale and monitor for us.

Cloud Run: Container to production in seconds | Google Cloud

Send feedback Build and deploy scalable containerized apps written in any language (including Go, Python, Java, Node.js, .NET, and Ruby) on a fully managed platform. New customers get $300 in free credits to spend on Cloud Run. All customers get 2 million requests free per month, not charged against your credits.

Web App Deployment - AWS Elastic Beanstalk - Amazon Web Services

Deploy and scale web applications Upload and deploy web applications in a simplified, fast way. Focus on writing code instead of provisioning and managing infrastructure. Select and retain full control of the optimal AWS resources for powering your applications. Use adjustable settings to scale your application for handling peaks in traffic, while minimizing costs.

• GCP interface was easier to understand

• Cloud run was easy to deploy and setup compared with Elastic Beanstalk.

• We planned to use Firebase Auth and BigQuery. So keeping all in the same place will simplify the infra maintenance.

Bonus: Vercel & Testin g Environments

• Vercel automatically generates testing environments for each PR.

• We use GitHub Action to create a DB based on the branch name.

• After a branch is deleted, the DB is also destroyed.

• Vercel also generates our testing environment for our Admin and Web apps
