Toptal Developers

@resonant_theory @toptal Hello @resonant_theory! Our tutorial did not cover wired sensors because they are difficult to install and weren't used by the author in his build. There is no reason why one couldn't use wired sensors. What matters for our tutorial is sensor input, not the type of sensor used.

Have you ever wanted to use Redux with features like React Query provides? The latest addition to Redux Toolkit, RTK Query, lets you do exactly that. #React #Redux #RTK #RTKQuery. topt.al/vqcggk

The ever-increasing mountain of data can be daunting. But a few lines of code go a long way! Dive into graph analysis (visual and non-visual) with @f__albanese's quick, hands-on #Python/#NetworkX tutorial. @datascinews #DataScience #DataVisualization topt.al/KvcB8m

Routing code is essential to #ExpressJS apps yet it often remains subpar until the scope of the app makes it more difficult to refactor. How about a centralized approach that also enables #JS promises? @AthulExe @UseExpressJS @bterlson @javascriptdaily topt.al/JGcGbk

State management is essential in #React development, and it is even more important when creating enterprise-grade applications. Which tools and libraries should you be using? Is #Redux still king of the hill? Let's take a closer look. toptal.com/react/react-st…

Visual regression testing is not a novel concept, but #QA specialists sometimes need to rely on unconventional tools and approaches to implement it. Here's how QA teams can leverage Cypress to run visual regression tests. toptal.com/web-qa/ui-visu…

Is #Redux still the go-to solution for state management in enterprise-level #React applications? What about #MobX and Recoil? Let's compare them and see which is a better fit for enterprise users. toptal.com/react/react-st…

@phry @dr_dimaka @toptal It's been corrected—thank you! :)

@dr_dimaka @toptal Minor nitpick: Dan Abramov did not create React, but joined the React team long after co-creating Redux.

Following the update of Picasso, our in-house component library, @Toptal #QA specialists employed UI testing and Cypress to run visual regression tests without resorting to specialized tools. Here is how and why they chose this approach. toptal.com/web-qa/ui-visu…

UMN's recent "hypocrite commits" to the #Linux #kernel raised ire but also raised issues about #OpenSource communities and code. Kernel maintainers dealt with it, but is it business as usual downstream? @mmcdonald10 asks developers and #SecOps experts. topt.al/4GcXVj

Build REST APIs fast? Sure. Endure and scale? Add: - Databases - Convenient-but-secure authentication - Validation and permissions systems - Automated tests - Docker @NodeJS #ExpressJS #TypeScript #API #MongoDB #JWT #MochaJS #ChaiJS #SuperTest #Docker topt.al/XGcr6A

#SQL can be deceptively simple. Ever add an index without seeing a speed benefit? Or partition a table, only to have maintenance time skyrocket? This final part of our series is for you. @SQLPerfTips #Index #Database #Performance #Tutorial #SQLHelp topt.al/BAcMbM

Repetitive #Scala code? Yes, it can happen in real life. And that's when the powerful macros and quick quasiquotes syntax of Scala save the day, keeping your code clean and maintainable. topt.al/z6cBy7

#Scala is great for keeping code DRY, but what can you do if a third-party library leaves you no choice but to repeat yourself? Get macros to do the repeating for you with the pleasant syntax of Scala quasiquotes. @FelixMulder @ShadajL @alxarchambault topt.al/z6cBy7
