The PUT was always sent to 127.0.0.1, which is nothing inside the container, so uploads failed whenever the web player did not run on the same host as SeaweedFS. Take an optional S3_UPLOAD_ENDPOINT instead (the compose stacks point it at seaweedfs:8333) and fall back to the host in the presigned URL. The signed Host header is preserved either way, so the signature still matches.
sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project
npx sv create my-app
To recreate this project with the same configuration:
# recreate this project
npx sv@0.16.2 create --template minimal --types ts --add tailwindcss="plugins:none" --no-download-check --install npm web-player
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
