Freshbooks - Sponsor Get a 30 day free trial of Freshbooks at freshbooks.com/syntax and put SYNTAX in the “How did you hear about us?” section. Show Notes 1:35 - Q: I prefer using grid-row and grid-column instead of grid-area. But is grid-area more performant? For example, in Flexbox, it’s a best practice to use the shorthand flex property instead of writing out flex-grow, flex-shrink and flex-basis. 4:04 - Q: Do you have any advice how to deploy an application? What do you think about AWS, Zeit, Heroku, Firebase? Do you use automation tools like Circle CI or Buddy.works? I also wonder if we should keep whole application on one server, or split it up. 9:36 - Q: A career advice question: I’m best at being a front-end/javascript developer - but in a quest to my make job(s) easier, I’ve also been getting into fullstack architecture - namely CI/CD (TravisCI, GitlabCI) and Kubernetes. I’m feeling like I’m spreading myself a little thin, and I guess I’m just finding it a bit frustrating (configuring Kubernetes is a lot of bashing your head against the wall). I know that my skills as a front-end developer are already valuable, whereas I can’t say the same for my Kubernetes/CICD skillset. I’m wondering whether I should narrow my scope a bit. Maybe this is just the frustrating hump I’m climbing over, and in six months I’ll be happy with where I’m at, but interested to hear your thoughts. One thing I’ve been thinking about is, maybe I should step back from the network architecture type stuff (ie. Kubernetes) and focus more on DevOps that is closer to the front-end stack (ie. writing tests, VSCode tooling, commit hooks, CI tools, etc.). 13:07 - Q: Do you think Typescript adds value to React, or more complexity than value? When should you choose Typescript for a project? 18:09 - Q: I am in a well known Bootcamp, and as of right now (from what they have taught us) this is what I am working with: HTML/CSS, JavaScript, jQuery, Node, Express, SQL, Auth, MVC, APIs, React, Redux. As we finish off the program, they are going over Java. I do want to learn Java, however I feel like my time would be better spent fine-tuning my knowledge on my stack. And I can learn Java at some other time. Do you recommend that I fully engage with Java and try to absorb some of the basics and fundamentals now, or do you recommend that I take this last month we have here and strengthen my current skills so I do better during my technical interviews? And by the way thanks for everything you do, it helps :) 22:02 - Q: Have you seen the live coding going on at Twitch? Thoughts? Maybe a Syntax stream in the future? There’s a good list at livecoders.dev. Thanks for all you do. Keep killin’ it! 26:11 - Q: How do you handle people (i.e. C# bastards) who think JavaScript is a joke and is going to be overthrown by Blazor or some other C# library framework? Can’t we all just get along and live in the same industry? I’m having a hard time being the adult in these kinds of responses around the web, and in random discussions with people I know very well. 29:55 - Q: There are plenty of places saying that it is important to secure API keys by not embedding them in front-end code. Cool. I’m on board! But there is not many that tell you specifically how to do this. How do you safely use an API key in a CRUD project? 34:15 - Q: Do you plan to launch a Syntax.fm app? 45:49 - Q: I was hired as a junior developer at a company in the last year. It’s my first development job and I was so excited. The interview and application were all about React and fullstack development. However now that I’ve been here a while, I have found out the company does primarily dev ops work. None of this was mentioned in the interview or application, but it looks like soon it will be the majority of my workload. I am feeling very discouraged and was wondering what you guys would do in this situation?

Data Temporary client side data From forms, button clicks, etc. Cached server data Data from API UI status AKA isModalOpen isToggled 12:48 - Global state vs. Local state Ask yourself: does the data need to be accessed outside this component? If data does need to be accessed a little higher, you can simply move where that state lives. React calls this “lifting state”. Do you count Apollo API calls as global state? 21:15 - Managing Local state useState, setState Passing state & update functions down State machines 31:12 - Approaches to Global state Redux Complicated, hard to learn Very useful, organized and structured Actions, reducers and more Time traveling do to nature of store Immutability Tons of Redux based hooks libs Mobx Based on Observables An Observable is like a Stream and allows to pass zero or more events where the callback is called for each event. Often Observable is preferred over Promise because it provides the features of Promise and more. Context Functions just work and update global state.
