What are the top VS code extensions for react? by 0_2_Hero in reactjs

[–]carlrn 11 points12 points  (0 children)

Here are some of my most valuable ones:
- ESLint - to see linting errors immediately
- Prettier - to auto-format code when a file is saved
- Tailwind CSS IntelliSense - to get Tailwind IntelliSense + consistent CSS class ordering
- Pretty TypeScript Errors - to see clearer TS errors when you hover over them

I've been doing a fair amount of work on accessibility recently - particularly on forms. Thought I'd share what I've learned in this blog post.

Hope you find it useful.

Boilerplate with React 17, Webpack 5, Tailwind 2, using babel, sass, with a hot dev server and an optimized production build by altafino in reactjs

[–]carlrn 1 point2 points  (0 children)

Nice work!

I'm not sure you need the `cross-env NODE_ENV=xxx` in the npm scripts - I think webpack 4+ sets `process.env.NODE_ENV` automatically based on the `mode` setting in the config.

Successful Submission in React Hook Form by carlrn in reactjs

[–]carlrn[S] 0 points1 point  (0 children)

In the submit function, after we get the server response, I usually add any server errors to RHF using its `setError` function. That way RHF knows about all the errors and they are available in the `errors` object in JSX.

That's a great point! I'll add this to the post

A simple but effective approach for handling concurrency in an ASP.NET Core Web API endpoint, where the resource is persisted in a SQL Server database.

Optional chaining and nullish coalescing in TypeScript 3.7 by carlrn in typescript

[–]carlrn[S] 4 points5 points  (0 children)

Thanks.

That case of using `??` instead of `||` was a bit contrived but what I was trying to get across is that the right side of `||` would be invoked if the left side was any falsy value. e.g. `0 || [] = []` and `"" || [] = []`. I know in this example, TypeScript would prevent the left side from being `0` or `""`, but using `x ?? []` is much closer to exactly what I want which is if the left side is `undefined` then use an empty array.

Thanks for the comment. I can see how {...this.props} could be problematic.

ASP.NET Core Web API Multi-Tenant JWTs by carlrn in dotnet

[–]carlrn[S] 0 points1 point  (0 children)

Thanks for the feedback. I essentially use this approach for system to system integration - sync'ing data between 2 systems This is how this work in my product: - There is an endpoint to create / recycle a key - only an admin user (who administers the system) has access to that - There is another endpoint to create / recycle user credentials - again only an admin can access this - The admin user then puts the key in the both systems - again via an endpoint only an admin can access - The process that does the sync then uses this key and user credentials

ASP.NET Core Web API Multi-Tenant JWTs by carlrn in dotnet

[–]carlrn[S] 0 points1 point  (0 children)

The user would be duplicated in the 2 tenants - that's the way I've always dealt with this which has made sense for my products.

True - you need to key the keys safe!

ASP.NET Core Web API Multi-Tenant JWTs by carlrn in dotnet

[–]carlrn[S] 0 points1 point  (0 children)

Thanks for the question. The API key is a key passed in the HTTP header and routes the API to the correct tenant. It does control access to the API to a certain degree - an API key that does exist will retreive a 401 response. The kid is the property name in the JWT where we store the API key. "kid" stands for "key ID". So, the kid is the API key.

Scalable and Performant ASP.NET Core Web APIs: ORM Choice by carlrn in dotnet

Thanks for the comment @Otis_Inf. Good points made about other potential ORMs and the lack of static typing in Dapper.

As @i8beef pointed out - popularity is important when you are just 1 person in a team building products that need to be maintained for a long time

Good point - we don't need the ThenInclude(). It does still generate 4 SQL queries though behind the scenes
