better-sqlite3 VS Nest

In the second video of the series, we are separating routers and adding SQLite, Better SQLite 3, Database to the application to show access to context for performing a simple query and mutation.

If I were charged with this task I'd probably take an actual SQLite DB and write methods to parse data from text files, then process it within SQLite, and serialize it back to the text file when an API method is called or after each processing step. A fresh DB engine, fully re-implemented to match SQLite's API is insane unless you're a prodigy or have a sizable team and will come with numerous downsides. I can recommend https://github.com/WiseLibs/better-sqlite3 and https://github.com/loveencounterflow/dbay

better-sqlite3 is orders of magnitude faster than the async SQLite bindings. We found this to be true when testing SQLite options for Notion's desktop app anyways.

Better SQLite is a wrapper around the SQLite database engine that provides a number of improvements over the standard SQLite API. One of those benefits is type safety, Better SQLite uses TypeScript to provide type safety for queries, which can help to prevent errors.

better-sqlite3 does the job synchronously

I used better-sqlite3 . It is simple to use as it is synchronous. I don't know if it scales good (at least the docs say it) but works great for my small use cases.

Kent's recommended NodeJS module, `better-sqlite3`, has some very nifty features including the creation of JavaScript user-defined functions[0] that (if I understand this right) can be called from SQLite. Combined with TRIGGERs, I wonder if it might fire a function within the app when an UPDATE/INSERT happens from a different process? (This is me wondering out loud, I don't actually know.)

I also recommend checking out Replicache[1] and alternatives, which may be a better way to handle the networking and database replication so that it doesn't rely on the underlying DB.

When using the NestJS framework, sometimes you may need to change some default timeout. You can define them just like you'd do in a plain Node.js HTTP server like so:

Back: a graphQL server built with Nestjs

NestJS - opinionated more scalable, but harder to learn docs

Pragmatically, we can apply this to a Nest application by creating an Interface for our services, separating the Presenter layer (Controller) from the Use Case (Services):

It’s a text document that contains all the commands a user could call to assemble an image. Let’s check an example of a Dockerfile for a nodejs app in this case it will be a NestJS app and then explain each part.

describe('Create bookmarks', () => { const dto: CreateBookmarkDto = { title: 'NestJS', link: 'https://nestjs.com/', }; it('should create bookmark', () => { return pactum .spec() .post('/bookmarks') .withHeaders({ Authorization: 'Bearer $S{userAt}', }) .withBody(dto) .expectStatus(201) .stores('bookmarkId', 'id')//store the bookmark id in the variable bookmarkId .expectBodyContains(dto.title) .expectBodyContains(dto.link) }); });

In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

The purpose of this article is to provide a step-by-step guide for implementing authentication system in a NestJS project using the Passport middleware module.

That's exactly where I am. My manager gave me these links, that cover a lot of those words the backend uses, so I can identify what they mean and how to use them. 1.
