expo VS TypeORM

I am using expo setup with tabs template.

Before we begin working on our project, we must set it up and install all the necessary dependencies. We will be using Expo for this project. Expo is a React Native management tool that handles a lot of heavy stuff for us, such as efficiently compiling code and assets, as well as provides us with a productive development environment. Also we will be using Typescript for this project, but don't worry, the process is practically identical to Javascript, so if you don't know Typescript that's fine. This article assumes some basic understanding of React and React Native , such as components, hooks and state. You must also have Node.js installed on your computer.

Expo saves us from the complex configurations required to create a native application with the React Native CLI, making it the easiest and fastest way to build and publish React Native apps.

- Try to unblock usage of Google Maps in my ReactNative Android, iOS and Web App. Context: "https://github.com/expo/expo/issues/23347#issuecomment-16264...

- Provide financial report to investors (this will likely take at least two blocks)

- Fix initial Zoom setting for Google Maps in my app for web. Context: https://github.com/teovillanueva/react-native-web-maps/issue...

- Check on analytics + user enqueries and write (back) to at least 3 of our most active users in the last couple of days

Timeblock exhausted. Posting this and jumping on first task from above.

But some bugs don't get fixed for years. E.g. there was an issue with expo-secure-store not working well on android after app reinstallatiins. It apparently got fixed now 5 years after it was reported: expo-secure-store bug

If you use Sequalize, TypeORM or for MongoDB, we have Mongoose these types of ORM tools, then you are safe by default because these help us against the SQL query injection attacks by default.

We decided to use MySQL for a database. and TypeOrm for ORM. The ER diagram is provided below. For example, the task_assignments table holds information about user assignments to tasks. While in DDD, there is a pattern to design denormalized tables that reflect the structure of domain objects more directly, but this time, a more conventional table design was chosen. TypeOrm models:

How does this compare to using directly an ORM lib that supports browser like TypeORM [0] via SQL.js [1]?

* Patch a third-party library that was setting an HTTP header to `null`. NodeJS handles this case just fine, but Deno throws an error [2].

After all of that work, I finally was able to use Deno in my project. It was really cool! Unfortunately, both VS Code and IntelliJ with Deno are essentially unusable [3]. Or, at least, unacceptably slow compared to what I had with NodeJS.

TypeORM is a very convenient ORM for JS apps. We use it with NestJS and running it on NodeJS.

We are going to start using TypeORM as an ORM to help us interact with Postgres, but we also have an example of using Prisma in the future and everything that we have to adapt to switch the ORMs if necessary. At the end we are implementing neon.tech as a production database, right? 😉

TypeORM is a popular Object-Relational Mapping (ORM) library for Node.js. It provides a high-level abstraction over relational databases, making it easy to perform CRUD (Create, Read, Update, Delete) operations.

TypeORM places its focus on TypeScript and JavaScript (ES7+) development. It offers compatibility with various database systems, including MySQL, PostgreSQL, SQLite, and MongoDB. What sets TypeORM apart is its robust integration with TypeScript. It provides a user-friendly experience with a convenient decorator-based syntax for defining entities and relationships. Additionally, TypeORM supports the repository pattern and enables eager loading, enhancing its versatility for developers.

ᴬ typeorm officially supports mssql@v9, but the support for the custom stream builder was added in mssql@v10. Since mssql is a peer dependency of typeorm, you can force override it and use the Cloud SQL Connector with typeorm. There is an open PR to add support for mssql@v10 in typeorm.
