If you’re creating a developer tool, you’re bound to run into this dilemmaāyou know the inner workings of it really well, but others don’t. And without solid documentation and samples to follow, it can be challenging for another person to get started. Friction with the tools we use can contribute to burnout, inhibit creativity and slow down innovation.
Developer experience (DX) is becoming integral for any software company to consider. I recently met with Christine Spang, CTO and co-founder of Nylas, to consider the benefits of investing in developer experience. Below, we’ll take a look at what exactly DX is and consider some best practices for implementing it.
What is Developer Experience?
Developer experience (DX) is similar to user experience but for developer-facing tools. DX considers the developer’s journey while developing with a certain framework, language or platform. “Developer experience is the amount of friction a developer experiences between having clarity on what they want to implement and getting to the point where you have created that thing,” said Spang.
For example, consider integrating with an API to solve a common use case like payments integration. There are many steps involved here, from reading the reference documentation to getting an API key, testing calls and understanding how the service responds. After developers initially integrate the API into their application, they may also have to make continual updates as the service versions. Throughout this journey, DX can be thought of as “how hard it is to figure out how to translate from idea to output,” said Spang.
It’s also important to note that DX isn’t only relegated to public-facing platforms. Having a quality developer experience is just as crucial for internal software. The urgency to improve internal developer experience is increasing with the surge of APIs being developed, especially since the majority of them (58%) are private APIs, according to Postman’s 2022 State of API Report. Depending on the size of a company, internal DX can encompass many areas.
Best Practices for Investing in Developer Experience
So, what are some methods to improve developer experience across the board? Well, having up-to-date documentation, code samples, better examples and standardized documentation rank high as positive developer experience traits. Spang also shared some helpful best practices to improve DX:
Provide scaffolding for the most common cases. Measure patterns around the kind of things people are building with the platform and offer scaffolding to support the common use cases. This might equate to a getting started guide for a common scenario.
Offer sample code libraries. It’s a lot easier to edit code than write it from scratch. With that in mind, create pre-baked environments where developers can play around. Offering working apps, use case templates and glue code can be a practical means to help developers get going more seamlessly.
Start with the reference manual. Walkthroughs and sample code should never replace a complete reference manual. It’s essential to have up-to-date documentation to cater to advanced users from the get-go. From here, you can generate Postman Collections or interactive sandboxes built around the reference specification.
Measure DX success and iterate. One way to monitor developer experience metrics is to record the onboarding flow and measure conversion rates. Where APIs are concerned, this can be tracked by asking how many people get through to making calls? What is the mean time it takes to make the first call? Knowing such metrics can inform how effective your tool’s self-service features are.
One point that’s important for DX is walking the fine line between too much custom work and focusing on the core project. On that note, Spang recommended “making sure whatever you’re building maps to the overall vision of the company.” In essence, if you’re not a consulting shop but a product company, you should stay true to that objective.
“You want to make the path for what people commonly want to do very easy,” said Spang. “Yet, you don’t want advanced users to feel constrained by the platform.”
Examples of Quality Developer Experiences
For those creating developer-facing services, it’s helpful to have a framework to model. So, what are some examples of quality developer experiences?
Well, top public APIs are great examples of where the bar is set for developer expectations these days, said Spangāservices like Twilio or Stripe demonstrate relatively seamless developer journeys. Spang also pointed to companies with a strong DevOps and CI/CD background, like Etsy, who have for years invested in usable backend infrastructure that accelerates internal development.
For other sources of quality developer experience, consider the high-ranking developer-favorite technologies from the latest 2022 Stack Overflow survey. Engineers love working with technologies such as PostgreSQL, AWS, Phoneix and Docker. The newer, trending languages tend to be increasingly usable, too. For example, 86% of developers said they love working with Rust while 76.65% dread working with Objective-C.
The Overall Benefits of DX
An investment into developer experience can help improve agility and developer satisfaction, said Spang. For one, an easier path for development increases the velocity in how you ship and evolve projects over time. Secondly, developer experience equates to less burnout and less turnover, both of which can have real business impacts.
The software development industry is growing like wildfire, bringing in waves of entry-level developers each year. Interestingly, the average experience level is decreasing, increasing the need for more abstracted tools and toolkits, said Spang. In this environment, developer experience undoubtedly shines as a competitive advantage.
So, if you’re creating developer-facing tools, consider the experience others will have when using them. Increasing developer experience may just be a defining factor in the project’s success and the long-term happiness of your developer community.
