Dynamic subdomains
Hi, I would like to setup custom subdomain to act like a slug, something like: [slug].mysite.com. I thought of using nginx that reverse proxy that will swap the subdomain to the slug in the background. So something like this: subdomain.mysite.com/hello -> mysite.com/subdomain/hello. Do you know any better method to achieve the same result?

Docker & Nginx - ports
Hi, I am running Docker containers on my VPS and I'd like to deploy there an API with Nginx config. Nginx uses by default ports 80 and 443, but those ports are already taken by Nginx which is running in non docker environment. Can I run another nginx (in docker) on this VPS if those ports are taken?

Override ENV variables inside Docker Compose
Hey, I have those ENV variables for my docker compose config. There's one problem, inside docker I have to specific DB_HOST {container_name}, so I've tried to override it. 
DB_HOST=localhost
DB_USER=

DB_PORT=

DATABASE_URL=mysql://${DB_USER}:${DB_PASSWORD}@${DB_HOST}:${DB_PORT}/${DB_NAME}
DB_HOST=localhost
DB_USER=
DB_PASSWORD=
DB_NAME=
DB_PORT=

DATABASE_URL=mysql://${DB_USER}:${DB_PASSWORD}@${DB_HOST}:${DB_PORT}/${DB_NAME}
env_file:
  - .env
environment:
  DB_HOST: mysql # Rewrite the `localhost` host, but this won't override the `DATABASE_URL` ENV
env_file:

environment:
  DB_HOST: mysql # Rewrite the `localhost` host, but this won't override the `DATABASE_URL` ENV

React immutability performance
Hi! Is it possible to avoid calling renderPosts every time when filteredPosts gets mutated? filteredPosts is mutated because state search value changes, but actually the value of filteredPosts (array of objects) did not (in case the search expression is not too specific) Can I handle this mutability in React? 
const filteredPosts = useMemo(() => {
  return posts.filter(
    (post) => post.title.includes(search) || post.excerpt?.includes(search)
  );
}, [posts, search]);

const renderPosts = useCallback(() => {
  console.log('renderPosts');

  // return filteredPosts.map ...
}, [filteredPosts]);
const filteredPosts = useMemo(() => {
  return posts.filter(
    (post) => post.title.includes(search) || post.excerpt?.includes(search)
  );
}, [posts, search]);

const renderPosts = useCallback(() => {
  console.log('renderPosts');

  // return filteredPosts.map ...
}, [filteredPosts]);

Strategy to test components in React
Hey, I am new into testing and I haven't test anything much before. I am still getting stuck about theory what should I test and what shouldn't. For example here. I have component Heading that takes prop level which is number between 1 and 6. Is this test useless? And if so, what test would you write for this specific component? 
const levels = [1, 2, 3, 4, 5, 6] as const;

it.each(levels)('should rener heading level %s', (level: HeadingLevel) => {
  render(<Heading level={level}>Heading {level}</Heading>);

  expect(screen.getByRole('heading', { level })).toBeInTheDocument();
});
const levels = [1, 2, 3, 4, 5, 6] as const;

  expect(screen.getByRole('heading', { level })).toBeInTheDocument();
});

Zod - sort schema
Hi. I am adding sort option to prisma findMany query. Since I don't know zod very well, I could not think of any possible type-safe solution. Sort format should be: columnFieldName:orderType, so for example: firstName:desc. I made my types from @prisma/client, but don't know how to add them to tRPC input. Is it even possible? 
type ColumnField = keyof Astronaut;
type Order = "desc" | "asc";

getAll: t.procedure
  .input(z.object({ sort: z.string().optional() }))
  .query(({ ctx, input }) => {
    const [col, order] = input.sort?.split(":") as any;

    return ctx.prisma.astronaut.findMany({
      orderBy: {
        [col]: order,
      },
    });
  })
type ColumnField = keyof Astronaut;
type Order = "desc" | "asc";

getAll: t.procedure
  .input(z.object({ sort: z.string().optional() }))
  .query(({ ctx, input }) => {

    return ctx.prisma.astronaut.findMany({
      orderBy: {
        [col]: order,
      },
    });

React Query - Update data after successful mutation
Using vanilla react query I was used to use one of these options. What are the options with tRPC? Since queryClient doesn't provide any of these methods. const queryClient = trpc.useContext(); 
// Normal React Query
queryClient.setQueryData(['posts', id], newPost)
queryClient.invalidateQueries(['posts', id, 'comments'])
// Normal React Query
queryClient.setQueryData(['posts', id], newPost)
queryClient.invalidateQueries(['posts', id, 'comments'])

Next.js - ReactQuery data is being refetched everytime route changes.
Hello. I made this simple demo, where react query forces refetch every time route changes, I want to disable this behavior. Is it possible? It does refetch only when previous response has been unsuccessful. In my specific example where I am getting user from API, I don't really want this kind of behavior, because it shows loading animation on every page change. My default query client options: 
defaultOptions: {
  queries: {
    refetchOnMount: false,
    refetchOnWindowFocus: false,
    refetchOnReconnect: false
  }
}
defaultOptions: {
  queries: {
    refetchOnMount: false,
    refetchOnWindowFocus: false,
    refetchOnReconnect: false
  }
}
const { data: me, isLoading } = useQuery(
  ["getUser"],
  () => fetch("https://api.com/api/me").then((res) => res.json()),
  {
    retry: 0,
    staleTime: 1000 * 60 * 60 * 8
  }
);
const { data: me, isLoading } = useQuery(
  ["getUser"],
  () => fetch("https://api.com/api/me").then((res) => res.json()),
  {
    retry: 0,
    staleTime: 1000 * 60 * 60 * 8
  }
);

tRPC, ssr specific route
Hello. I'm migrating to tRPC and I ran into this specific issue. In this scenario I prefetch data on server using getServerSideProps and then pass them to initialData inside useQuery. I use it for SEO purposes. What can I do when I'm using tRPC, I'm unable to do the fetch on server using useQuery. I know there's option ssr: true, but I don't want to all routes to run on SSR just because of this one specific case. Thanks. 
const { data: track } = useQuery(
  ['track', router.query.id],
  ({ signal }) =>
    axios
      .get(`/api/spotify/track/${String(router.query.id)}`, { signal })
      .then((res) => res.data),
  { enabled: !!router.query.id, initialData }
);

export const getServerSideProps: GetServerSideProps = async (context) => {
  context.res.setHeader(
    'Cache-Control',
    'public, s-maxage=86400, stale-while-revalidate=86400'
  );

  return axios
    .get(`${getBaseUrl()}/api/spotify/track/${context.query.id}`)
    .then(({ data }) => ({ props: { initialData: data } }));
};
const { data: track } = useQuery(
  ['track', router.query.id],
  ({ signal }) =>
    axios
      .get(`/api/spotify/track/${String(router.query.id)}`, { signal })
      .then((res) => res.data),
  { enabled: !!router.query.id, initialData }
);

export const getServerSideProps: GetServerSideProps = async (context) => {
  context.res.setHeader(
    'Cache-Control',
    'public, s-maxage=86400, stale-while-revalidate=86400'
  );

  return axios
    .get(`${getBaseUrl()}/api/spotify/track/${context.query.id}`)
    .then(({ data }) => ({ props: { initialData: data } }));
};
