How can I dynamically set the API endpoint during React app deployment?

Seeking a flexible method to configure API URLs for a React deployment. My solution uses environment setup:

const serviceEndpoint = process.env.REACT_SERVICE_URL || 'http://localhost:4000';

hey, i’ve tinkered with external config files to set endpoints dinyamically. curious if anyone else has faced env var casing probs? how did u manage it in your deployment? keen to hear other workaround ideas.

i tried loading config data during app startup via a json file, then setting api endpoints based on that. its a neat workaround to avoid build time limits and allows quick tweaks in production

Based on my experience, using an asynchronous configuration fetch during application startup has proven effective. In one of my projects, I employed a lightweight JSON configuration that was loaded before the React app initialized. This method not only improved overall flexibility but also eliminated the need for constant rebuilds when modifying API endpoints. It ensured that the environment was tailored at run-time, thereby decoupling the deployment setup from the static build configuration. This strategy also simplified maintenance in production while preserving configuration integrity.

hey, i’ve jused a dynamic config injection where a littlt script grabs env info at runtime. it works nicely, but had some caching hiccups. has any1 els experienced similar issues? what did u do to smoothen the deployment vibe?

been using a runtime injected variable config in my docker setup, works pretty well without rebuilds. had to tweak a bit for async loading but overall its a clean solution for dynamically setting endpoints at deployment
