AI Use Case Walkthrough: Building Marketing Software Part 2

This is part two in our series of an AI use case walkthrough building software for the non-technical person like the marketer. In part one, we did the requirements gathering for our app to walk through all the considerations that we would need to build this app. As a reminder, we're building kind of a fun fun puzzle game. So in part two, we're gonna pick up where we left off with library construction. I'm using Google's Gemini in AI Studio, but again, you're free to use the AI tool of your choice, Chat GPT.

I would say for the average non-technical marketer, your best tool of choice would probably be Anthropic Claude, because it's really good at coding. If you're going to be building a big app, uh then probably you're gonna use Google Gemini because it has the largest working memory. Today we're gonna start building the library construction. What we're specifically talking about here is building the best practices documents, the knowledge blocks, like we saw in in part one for the coding environment for the technology. This is important because we want to specify what are really good best practices for writing this kind of software.

And then when we start writing it, the AI model will have those guidelines to follow, things like error tracking and logging and stuff like that. To do this, we're gonna use the Trust Insights Repel framework, roll action prime prompt evaluate and learn, uh, as we did in the previous steps. So let's go ahead and go into. I'm gonna pick up where we left off. So we've already done the requirements gathering.

Uh, what I want to say do next is I need to know what kind of best practices library to work with. Um, so far in this app, we are already almost 18,000 tokens, which is what about 14,000 words in. Um, so I'm gonna start by saying what are the best technologies like can't type today. Geez, libraries, frameworks, and languages best suited to meet our requirements for developing this app. And as you recall from the previous one, I'm gonna uh part of the episode.

I'm gonna save those requirements as markdown. When you do this, and you save it in your prompt library, you can see that you get a really, really nice extensive list of this is what the thing is gonna do. So the author here is going to be Gemini and uh trust insights.ai. And boy, do you think it's October 26, 2023? It is not.

This is January 12th, 2025. That tells you where uh where the knowledge cutoff of this thing is. Alright, so this is my in my prompt library now. I've stored the requirements for this app. Now I'm going to ask it what technologies are the best fit for this.

We're gonna ask this question, get the answers, and then build out the best practices library client side, HTML5, CSS, JavaScript, framework, React for the user interface, emoji picker for React, um, UI components, material, let's see, server side, node.js for this minimal service eye component, uh, framework, express.js, SQLite for the database, and then JSON for the puzzles, npm or yarn for managing project dependencies, webpack or parcel, hosting versal, AWS, Netlify. I'm just gonna stick it on my website. Uh, analytics GA4, testing, React Testing Library. So these are all the potential technologies. Um it's uh it says the stack summary react and so on and so forth.

Say great. We are going to standardize on the React Node approach. Given these choices, show me now the revised tech stack. So we're gonna use React Node SQLite. So that is front end, back end and database.

So now we get a much more focused uh list of all the things that we're gonna be doing, and now our next step is to start building out um our best practices for these languages. So we're gonna start off by saying next, let's do the role. You are an expert JavaScript developer, skilled in node, React, and web-based application development. Today we're going to isolate best practices for coding in React and Node. What do you know about general best practices for creating robust high performance, high speed, resource efficient code in React and Node, specific to web based entertainment applications?

So really what I'm doing here is I am just parroting back what the tool set or a tool choices. I'm saying, hey, what do you think? Uh what are what are the best practices here? And what we're gonna be doing is we're gonna distill this down as we did in part one of taking all these ideas and things that typically go wrong and expert tips and tricks for both React and Node into a guide into a knowledge block. So it's spitting out that now.

So I'm gonna say, what are common mistakes in React and Node for web based games that less skilled developers often make? I'm gonna wait on this because I want to take this section here and I'm gonna put this in my comprehensive best practices guide. Instead of having it summarized because I don't want to lose any of this valuable information, I'm gonna just copy and paste all three chunks. Note that we're not coding, right? There's zero coding happening here.

This is literally just copy and pasting, but we're asking questions to have the model spit out its known best practices for these languages. If I wanted to, I could take maybe the documentation from the React website or the node.js website and actually feed that in as training data for this as well. Um that would be a way to get at even more great ideas. So I'm gonna put in the React best practices and the node best practices, and now I'm gonna ask that second follow-up question. We're gonna let it talk, and then we're gonna, while it's talking, I'm gonna write the third prompt, which is what are some expert tips and tricks in React and Node for web-based games.

Tricks of the trade, uncommon knowledge and approaches that we have not discussed yet. Okay, so it's coming up with our things to avoid guide. Alright, so it has spit out the things to avoid guide. I'm now going to copy that, put that in my prompt library, and you're you'll see here, I'm gonna just put some headings in to make this a little easier to see. So there's our best practices for in general.

Here are our mistakes to avoid, and then we're gonna have React and Node game development expert tips and tricks. And let's see how we're doing over here. Still coming up with things. Alright, our tips and tricks are done. So now I'm gonna copy that, go to my prompt library, paste that right in, trim out a little bit of the fluffy narrative.

What do we have? We have a gigantic set of best practices for this exact uh application. Now here's the question. Um, what do you do with this? Well, what we do with this is we use this as system instructions.

So in Claude, you could use system instructions in Chat GPT, you can use it as system instructions, and of course in Gemini you can do the same thing. I'm gonna create a new prompt now, and I'm gonna take that big huge document that I just uh did, and I'm gonna put the entire thing in. That is about 5,000 words of best practices, but what we've done is we've preloaded our AI to now be an expert coder in this whole setup. So what we've done in part two here is we have taken our, we've used generative AI to take our overall requirements and then build from those requirements our instructions for telling this model how it's going to code, how it should code, the things that it should not do. So this is part two.

Next, in part three, we're going to start framing out the application to understand just how complicated this is going to get.
