A short list of graphql relay style backends or libraries

I asked in the graphql discord server #relay channel, what people used to build their graphql relay style backends.
Here I’ll list the responses.

Language: Go
Toolkit: gqlgen with ent and entgql extension

I made a starter package one can clone and adapt. It uses openid-connect for authentication and postgresql as the data storage. It can also use sqlite in-memory for development purposes.
https://github.com/dlukt/graphql-backend-starter

Language: Scala
Toolkit: Caliban

Language: Node.js
Toolkit: Pothos

Another member of the graphql discord server created a starter package with Prisma, Pothos and Better Auth.
https://github.com/nkzw-tech/server-template

Language: Python
Toolkit: Strawberry GraphQL

Language: Elixir/Phoenix
Toolkit: Absinthe

Language: C#/.net
Toolkit: Chillicream

If you know more, please comment and I’ll extend the post

Remix JS: Does Remix use process.env or import.meta.env?

Does Remix use vite’s import.meta.env or process.env?

The answer is, both. However it’s better to rely on vite’s import.meta.env because of 2 things:
1. Only VITE_ prefixed environment variables are imported
2. It’s also available in the non-SSR context, while process.env is a NODE thing only and not propagated to the browser.

So what does that mean?

You can have a
.env.development
and a
.env.production
file in the project root and add things like

VITE_HTTP_ENDPOINT=http://localhost:8080/api/v1
VITE_OIDC_AUTHORITY=https://my.id.domain.tld

1 2	VITE_HTTP_ENDPOINT=http://localhost:8080/api/v1 VITE_OIDC_AUTHORITY=https://my.id.domain.tld

and you can access those variables with e.g.

const httpEndpoint = import.meta.env.VITE_HTTP_ENDPOINT
const oidcAuthority = import.meta.env.VITE_OIDC_AUTHORITY

1 2	const httpEndpoint = import.meta.env.VITE_HTTP_ENDPOINT const oidcAuthority = import.meta.env.VITE_OIDC_AUTHORITY

but this also gives you access to other variables, which are present by default

{
  BASE_URL: '/',
  DEV: true,
  MODE: 'development',
  PROD: false,
  SSR: true,
}

{

BASE_URL: '/',

DEV: true,

MODE: 'development',

PROD: false,

SSR: true,

}

Uncaught RangeError: date value is not finite in DateTimeFormat.format()

Playing with Flowbite React and their Datepicker component, I had data coming from the backend in this or similar form:

{
	"data": {
		"posts": {
			"edges": [
				{
					"node": {
						"id": "c57e4ea8-072e-4057-974f-bfb369504a57",
						"createdAt": "2024-10-24T12:21:20Z",
						"updatedAt": "2024-10-24T14:03:16Z",
						"title": "Jobangebot mit jemand ohne Namen",
						"body": "Dies ist ein Jobangebot von jemandem ohne Namen",
						"expires": true,
						"expireTime": "2024-10-31T23:00:00Z",
						"category": {
							"id": "df84950d-742b-4d07-9f11-04b8964bcb36",
							"title": "Jobangebote"
						},
						"profile": {
							"id": "0ce6ee59-4ebf-42cf-9c3a-69cf5e826b0b",
							"sub": "288686157058342913",
							"name": ""
						}
					}
				}
			]
		}
	}
}

"data": {

"posts": {

"edges": [

{

"node": {

React is a bit of a cringy special child. Angular, no problemo. Vue, no problemo.
Anyhow.

I have to set defaultValues in a React-hook-form form, because React is special with controlled and uncontrolled components.
aka

type AdminPostEditFormValues = {
    title: string,
    body: string,
    expires: boolean,
    expireTime: Date,
}
    const {control, handleSubmit, watch, formState: {errors}} = useForm<AdminPostEditFormValues>({
        defaultValues: {
            title: data?.posts?.edges[0]?.node?.title,
            body: data?.posts?.edges[0]?.node?.body,
            expires: data?.posts?.edges[0]?.node?.expires,
            expireTime: dayjs(data?.posts?.edges[0]?.node?.expireTime).toDate() || dayjs().toDate(),
        }
    })

type AdminPostEditFormValues = {

title: string,

body: string,

expires: boolean,

expireTime: Date,

}

const {control, handleSubmit, watch, formState: {errors}} = useForm<AdminPostEditFormValues>({

defaultValues: {

title: data?.posts?.edges[0]?.node?.title,

body: data?.posts?.edges[0]?.node?.body,

expires: data?.posts?.edges[0]?.node?.expires,

expireTime: dayjs(data?.posts?.edges[0]?.node?.expireTime).toDate() || dayjs().toDate(),

}

})

So, I’m using dayjs for my date/time stuff, and this line essentially means, parse the Date before assigning it to a form value (or create a new Date(), because React and controlled/uncontrolled forms is not a happy story).

            expireTime: dayjs(data?.posts?.edges[0]?.node?.expireTime).toDate() || dayjs().toDate(),

1	expireTime: dayjs(data?.posts?.edges[0]?.node?.expireTime).toDate() \|\| dayjs().toDate(),

TL;DR: Parse the date value coming from the backend into a Date object. e.g.

Date.parse("2024-10-31T23:00:00Z")

1	Date.parse("2024-10-31T23:00:00Z")
