Vue js vite app taking long time

I'm building an Exam AI app using Vue.js, Django DRF API, and OpenAI API. The app involves heavy operations like uploading files, sending them to my API, and then to the OpenAI API. The backend functionality works perfectly, but the frontend, specifically the dashboard, takes at least 1 minute to load. In the dashboard, there are multiple checks (e.g., verifying if the user is logged in or if they are an admin), which involve direct API calls instead of using local storage. Despite this, the backend handles these checks efficiently. However, I deployed my Vue.js app on Railway.app without building the app (I didn't run npm run build). Could this be the reason for the slow loading times on the dashboard? How can I solve this issue?

It will help if your app bundles and servers the build files. However, I am not sure that it is your actual issue. For an example on how to use Vite https://github.com/brody192/vite-react-template. This is Vite + react. But you can extract the Vite stuff for your use. The important things, are that you are building the files (they end up in dist) and then you serve them using Caddy as a file server. You can even stack Caddy's btw So, you should do the above. But regardless of that, I am not sure if it will actually fix your issue. I would also make sure that all of your services are in the same region. If serving the dist files doesn't help; someone else can help you debug further

So running build for vite, will crate a directory called dist. These are all static files but you need a way to serve said files to the user / client. To do that, you use Caddy, as seen in the example I sent. You will just need to add a PORT variable in railway. You can set it PORT=3000. I don't know what your build looks like. If you are letting railway handle it for you (not using docker or anything), you can just copy the nixpacks.toml. If you are using something like docker for your build; here is what I did

# official Bun image
# see all versions at https://hub.docker.com/r/oven/bun/tags
FROM oven/bun:latest as build
WORKDIR /app

COPY package.json bun.lockb .
RUN bun install --frozen-lockfile
COPY . .

RUN bun run build

FROM caddy:latest

copy --from=build /app/dist /dist/

COPY Caddyfile /etc/caddy/Caddyfile

RUN caddy fmt --overwrite /etc/caddy/Caddyfile

CMD exec caddy run --config /etc/caddy/Caddyfile --adapter caddyfile 2>&1

Actually, if you do it the way I show, you will also have to make 1 additional change.

- root * dist
---------
+ root * /dist

Can you show me your build logs? The top mainly. So we can see what it was already doing
