In order to avoid running into any bundling issues its better to use webpack. Schema changes cant be directly pushed to it. Similar to the earlier step obtain the connection variables for this production branch. That is through Netlify, Auth0. That's what it should be. We were working with the Prisma team partially to make this workflow work because initially there were some blockers to using Prisma with PlanetScale. I'm going to Netlify oh, wait. JASON LENGSTORF: Let's take the first one here. Uhhhha little bit higher. We'll use the Planetscale serverless driver, @planetscale/database, to work with Deno. So if anything needs to be done with. It's a really cool thing, but the problem with it is sometimes, every once in a while, it flashes and when it's on video, even one frame is too many so I've just largely not used it. And so, a serverless database, there's different pieces about it that is a little different. JASON LENGSTORF: And that was my mistake. In this guide we will create an API using serverless functions, then use PlanetScale and Prisma for data persistence. You're going to start dropping connections, requests are going to fail. This integration auto-generates connections strings and connects your Vercel projects to your PlanetScale database with zero config needed. PlanetScale Portals supports globally distributed applications. JASON LENGSTORF: I just realized something. Now, you just go tell us which one you're using or if you have a custom table name. It also creates binaries to run in different environments. Luckily with Prisma, you can maintain these relationships in your data and allow the use of referential actions by using Prismas ability to emulate referential integrity in the Prisma client. You can decide which PlanetScale database branch (i.e a development branch) you need to promote to production. Add an environment variable with a key of DATABASE_URL and select only the Preview environment option: Set the value to the connection string of your second PostgreSQL database. To keep things light, the API we'll create generates memes by allowing uploads of image templates, then generating new images with overlaid text. Do we want to initialize, like, a Next project and add a page to do an API route to do that, to get. I don't know. What else you got? JASON LENGSTORF: Let's get TV on the Radio. Netlify, Auth0.If you have gift subscriptions, thank you. JASON LENGSTORF: Okay. Okay. So, then we need to do more, I assume, because it's mad at me. Otherwise, you can sign up for a free account. In order for Prisma Migrate to work, we need our environment variables, those two environment variables and, Prisma does the nice thing of creating a file for us. What. TAYLOR BARNETT: Branches can be in different regions. JASON LENGSTORF: Yeah. Run here. https://www.netlify.com/blog/2021/11/15/deploy-a-dynamic-next.js-app-to-netlify-with-planetscales-branchable-serverless-database/, https://github.com/planetscale/nextjs-planetscale-starter, https://github.com/planetscale/nextjs-conf-2021. You can read the data. Referential actions allows you to define this behavior from the Prisma schema by passing in the onDelete and onUpdate arguments to the @relation attribute. What's is it version yeah, there it is. [Indiscernible] will have its own and then, like, Typer, whatever you're using.So, our schema is now on our main branch. The starting point is the Prisma Vercel example, which has four serverless REST endpoints configured as Next.js API Routes and a Next.js page that allows you to call the endpoints and display data. All over it. [Laughter]. Be sure to check out our F1 Championship Stats demo application and sample repository to find examples for use with Cloudflare Workers, Vercel Edge Functions, and Netlify Edge Functions. I guess we'll just do this for now? If we had written onDelete: Cascade, deleting a LitterBox would also automatically delete the Cats linked to it. id type-fest , https://github.com/sungvalley/express-ts-training/tree/20eaafd344593d34ec7059b3659127a34189b32d, Node.js + TypeScript + Express + Prisma + PlanetScale API, "../../infrastructure/prisma/repository/user", "../domain/repository/user/IUserRepository", domain/repository/user/IUserRepository.ts, infrastructure/prisma/repository/user/index.ts, "../../../../domain/repository/user/IUserRepository", https://zenn.dev/sungvalley/articles/4de76c12826709, https://www.prisma.io/docs/guides/database/using-prisma-with-planetscale, https://planetscale.com/docs/concepts/connection-strings. [Laughter]. When you're done, the .env file will look something like this: With the schema available and the connection details configured, you can push the Prisma schema to PlanetScale: Apps built with Nitric define their resources in code, you can write this in the root of any .js or .ts file. TAYLOR BARNETT: That's a new one for me. Rust Adventure. You can also use the PlanetScale CLI to create a database by running the following command: Terminal pscale db create star-app --region <REGION> Problems with this site? to build and deploy DB-powered Next.js apps! The Tuss wouldn't easily support other. TAYLOR BARNETT: It ends up having three tabs, usually, at that point. TAYLOR BARNETT: Besides starting to put in the model itself, no. We're going to move all of this up to I don't know I don't need that part. And do a space. TAYLOR BARNETT: I know you talked about it at Prisma Serverless Conf. But I do remember, like, the moment when it started being one of the competing services that you would watch videos on. "title": "Comparing Database Types: How Database Types Evolved to Meet Different Needs". PlanetScale is a MySQL-compatible serverless database that brings you scale, performance, and reliability without sacrificing developer experience. I can migrate? You do not yet have any data in the database, so the application returns an empty array: This API call uses Prisma to get all users in the database with their related profiles. Captions provided by White Coat Captioning (https://whitecoatcaptioning.com/). Prisma.song. Source database. TAYLOR BARNETT: I just wanted to say the Prisma Migrations thing, it's a thing a lot of ORMs do. Today's not the day. This works because you're already logged into the browser so we don't have to have you do a separate login. And then, you space again. The boilerplate code structure looks much like below. It's what really makes PlanetScale special. Somebody messaged me to let me know. The code is in the pages/api/posts.js file. I don't know any of the song names. That brought in what is the Git Flow and how do we work and have our code in these kind of separate environments, some ways. Cloak. If you do a P Scale Off login. Why does one need a serverless database versus a regular database? Putting all of these together we can update our schema.prisma file in following manner. So, let me switch us over to the desktop view here. Ah, crap! On the Configure Project screen, set the DATABASE_URL environment variable to the connection string for your PostgreSQL database: The database connection string has the following format: For example, on Supabase it looks similar to: Vercel will now deploy your application. We're going to call this one, hereokay. You can setup a Planetscale database via their CLI or straightly through the web console. All right. [Laughter]. If you want to travel back in time and learn about a past release, you can find all the shows from this quarter here: Some highlights of this quarter include the interviews with Prisma Ambassador Albin Groen about the Prisma Schema Builder, Serghei Ghidora about how Elsevier uses Prisma or Tana Berry, Prisma's new documentation lead. https://docs.planetscale.com/tutorials/automatic-prisma-migrations. But one of the things is, historically, I think where things were kind of going is, oh, maybe we can't use MySQL databases in this tradition way, anymore, because of these connection issues. If you encounter issues using MySQL packages with PlanetScale, use the serverless driver instead. Also, I see you making fun of me, Dom. This doesn't feel too far from that. Our Slack has almost 50k members and is a great place to ask questions, share feedback and initiate discussions all around Prisma. And referential integrity, this is interesting because I don't quite know what this means. TAYLOR BARNETT: And click on that Main and the schema at the top, you might have to click the refresh button because sometimes it hasn't pulled down. I need to turn this off, because we're not going to need it today. On the Create Git Repository screen, select GitHub. What got me clued into this was Chris Biscardi is doing Rust Adventures wait, where's Rust Adventures? JASON LENGSTORF: Hello, everyone. We do it in a very safe way, where it can still be running and all that going on while that merge is happening. We'll see how all that goes.So, I've created a database. TAYLOR BARNETT: I pasted it into DMs, if you want to make it a little bit faster, the code that I use for client. Same thing. JASON LENGSTORF: We've got roughly 15 minutes left in the episode so what we might want to do is let's seed some data in. Developers can create branches for development and push those to production when they are working as intended. I'll deal with that at a later date. Some of the biggest sites on the planet are all all the data is on MySQL. In the following example, audit is a Json field that accepts a read-only array: We wouldn't be where we are today without our amazing community of developers. There are two main workflows for Prisma Migrate: For brevity, this guide does not cover how to create migrations with prisma migrate dev. We're like, no, you still can use a MySQLcompatible database, you just need different infrastructure. There are several other options you can adopt in case if your setup is different to what we are using here. Five minutes. Once it's running you can test it with an HTTP request: Since we won't use the example function you can delete the functions/hello.ts file. Hurray. 1 . Well use the aws-nodejs-typescript serverless template to initialize the project. I did have one point where I remember where I did take software engineering interviews because I was debating going back.Data analytics API. It takes less than an hour so any pie that takes less than an hour, sign me up. Let me pull up TAYLOR BARNETT: And then, umURL is good. Which I have to do every 12 months because I don't, like, store recipes. But, they're also the experts that help teach the rest of us, and PlanetScale, how to build on top of the Tuss. JASON LENGSTORF: This is going on his permanent record. [Laughter]. As before, the connection string has the following format: You should see the DATABASE_URL environment variable for the preview environment in your list of environment variables: You have successfully deployed your application to Vercel. serverless-offline is added in order to emulate the Lambda API locally. So, we've got the latest P Scale CLI and I am now ready to well, I'm not quite ready because I have to log in, right? One of the other things that's cool about PlanetScale is it calls itself a serverless database and I think that there are there are a couple entries in this space, but I think PlanetScale's doing something interesting here. It's going to ask you. And then the database name. Let's do that. We've leaned really hard into MySQL because that is what is scaled so well with the Tuss. Headquartered in Sri Lanka, 99x is a technology company co-creating well-engineered, innovative digital products for the Scandinavian market. The latest version of the PlanetScale platform builds on other industry-first capabilities including branching and sharding with the addition of PlanetScale Imports, according to the vendor. If I take these dependencies out and I move them over into this package JSON and, then I take these dev dependencies and I move them into this package JSONand then, I can. This API call uses Prisma to delete any existing database records and load the database with test users, profiles, and posts, then returns the created users. JASON LENGSTORF: From PlanetScale used a Next API route. JASON LENGSTORF: Do a song title and a Spotify link? JASON LENGSTORF: Oooohhhh. Additionally, we're importing the bucket used to store template images templateImages from the resources directory. On PostgreSQL, MySQL, SQLite and Microsoft SQL Server, referential actions will be enforced by the database. We're big fans of. JASON LENGSTORF: Oh, so this gives you visual like, you can see things through time and space here? This will autoload. Not now. So, Smoking Out The Window. You would never do that work on your website.So, then okay. This will be a development branch. [Laughter]. [Laughter]. What am I forgetting? [Laughter]. The other cool thing about the merging is, like, especially for larger databases, that could be a pretty tricky thing to do.
