Why is my React app showing a blank page after deployment on Render?

Backend
1

Hey everyone! I’m stuck with a weird issue in my React app that uses Node.js and MongoDB. The backend is working perfectly, but when I deploy the static site for the frontend, I only see a blank page without any error messages.

I have two deployments on Render: one static site named ‘shoppe-globe’ for the frontend and a web service called ‘shoppe-globe-app’ for the backend, both from the same repository. My folder structure is set up for a Vite project, and my configuration files are in place. Below is a snippet from my package.json for reference:

{
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "start": "npm run server",
    "render-postbuild": "NPM_CONFIG_PRODUCTION=false npm install && npm run build"
  }
}

Any suggestions on what might be causing the blank page would be greatly appreciated. Thanks!

I’ve encountered similar issues with React deployments on Render. One common culprit is incorrect base path configuration. Ensure your vite.config.js includes the proper base path, typically ‘/’. Additionally, verify that your static site settings on Render are correct, especially the publish directory. It should match your build output folder, usually ‘dist’ for Vite projects. Lastly, check if your API calls use relative paths or if they’re hardcoded to localhost. Adjusting these factors often resolves the blank page problem without visible errors.

have u checked ur console for errors? sometimes render can be finicky with env variables. make sure ur api endpoints r correct and ur CORS settings allow requests from the frontend domain. also, double-check ur build output directory matches what render expects. good luck troubleshooting!

oooh, blank pages are SO frustrating! :tired_face: have you tried clearing your browser cache? sometimes that can help. also, maybe check if ur react router is configured correctly for the deployed environment? it could be a routing issue. what happens if u try accessing specific routes directly?
