A quick update since I originally published this story. Ben Duong pointed out a Serverless Framework plugin Serverless A

AWS’ API Gateway allows you to directly connect it to/proxy many other AWS services. This article discusses doing this with DynamoDB, as a way to create an API that adds data to DynamoDB, without needing to use a Lambda function. There are existing AWS docs on using API Gateway as a proxy for DynamoDB, however, as usual, those only cover how to do this in the AWS console. In particular, I’ll show how I set this up using the Serverless Framework (or CloudFormation, as the bulk is really just CloudFormation code), and how you transform the web request’s JSON so it can be directly PUT into DynamoDB. Finally, I’ll talk about how to then do post-processing of the data via DynamoDB Streams.

This alleviates the need for a Lambda, and avoids the cost of that. Not that Lambda is that expensive, but if this does wind up scaling to say millions (or hundreds of millions) of events per day, then that will be a meaningful savings. Furthermore, this is more maintainable and a simpler architecture, as it’s one less component to build and maintain.

The use case I have is an authenticated web API that takes in a potentially significant volume of events from mobile devices. This data will be stored in DynamoDB. As an additional constraint, the mobile app is sending via regular HTTP web calls, and doesn’t have the ability to use GraphQL (i.e. AppSync isn’t a possibility for this case). Finally, I want this particular API to be simple and very fast, and all the (time consuming) processing of the data will be done async. Thus, we can simply have the data come in via API Gateway and get injected directly into DynamoDB (with some basic data transformation, and integration of the user’s ID).

Another tool that can help you to have a more readable code, thus making it more maintainable, is a formatter. Like a linter, it works by identifying format problems based on rules. Some examples include using single- or double-quotes for strings, the length of the lines, etc.

It was a tough call to put this point in the article. I think this is the only one from the list that you can omit because you won’t always need CSS-in-JS. However, I also think it is worth knowing about its existence so you can decide if it adds value to your project.

By having the right tools, we can write code faster and better. This article discusses some of the tools that you should consider using when working on a React project to make your life as a developer easier.

The UX Collective donates US$1 for each article published in our platform. This story contributed to Bay Area Black Designers: a professional development community for Black people who are digital designers and researchers in the San Francisco Bay Area. By joining together in community, members share inspiration, connection, peer mentorship, professional development, resources, feedback, support, and resilience. Silence against systemic racism is not an option. Build the design community you believe in.

By having TypeScript, a linter, and a formatter, you will have a better experience while developing code. But those tools are not completely automated. Sometimes you will need to run a command in the console to run them. We sometimes forget to do it and end up pushing some bad code to our repositories, and this is where this tool shines.

nce is like showing up at a theme park. (Except some of the strangers there will become your best friends.) When the ride kicks in, it demands total concentration. Between bouts of intensity, you’ll have the chance to take a breath — trading stories, recommendations, and ideas.

By having TypeScript, a linter, and a formatter, you will have a better experience while developing code. But those tools are not completely automated.

Keeping with the topic of components, CSS-in-JS is something that you would want to explore for your project. It allows you to solve some complex situations that wouldn’t be easy to solve with pure CSS.

Testing is something you cannot avoid if you want to have a code that is maintainable. There are a lot of libraries for testing your code, but I think RTL is a good starting point since it is specialized in React.

Storybook is a tool for developing UI components in isolation. This means that Storybook allows you to see and interact with your components in an isolated way, similarly to how unit tests scope the testing of your component code.
