Say Goodbye to If-Else Chaos – Feature Flags for Everyone

If you’ve ever tried rolling out a new feature in a React app, you know the drill. You add a bunch of if-else statements, check environment variables, or maybe even maintain separate branches for different versions. It’s messy, error-prone, and worst of all—it doesn’t scale.

Meanwhile, big tech companies use feature flags to make these problems disappear. They roll out new features gradually, run A/B tests effortlessly, and toggle features on or off without redeploying. But if you're a startup or a solo developer, implementing feature flags yourself feels like overkill.

That’s exactly why we built FlagSwitch React—to bring powerful, enterprise-level feature management to everyone. And the best part? You don’t need if-else statements, and it works with just a single import.

One Import. No If-Else. Infinite Flexibility.

Imagine this: instead of writing convoluted logic like this—

import NewCheckout from "./NewCheckout";
import OldCheckout from "./OldCheckout";

const isFeatureEnabled = import.meta.env.VITE_FEATURES.CheckoutFlow.enabled;

export default function Checkout() {
  return isFeatureEnabled ? <NewCheckout /> : <OldCheckout />;
}
Enter fullscreen mode Exit fullscreen mode

—you just import and call one function:

import { flagSwitch } from "flagswitch-react";

// ./flag-switch.ts
export const loadFeatures = flagSwitch({
  features: {
    CheckoutFlow: {
      enabled: true,
      split: { MultiStepCheckout: 30, SingleStepCheckout: 70 },
    },
  },
});

// ./index.ts
import { loadFeatures } from "./flag-switch";

export const CheckoutFlow = loadFeatures('CheckoutFlow');
Enter fullscreen mode Exit fullscreen mode

Boom. No environment variables, no conditional rendering, no spaghetti code. Just clean, maintainable feature toggling that works right out of the box.

Feature Flags Without the Overhead

With FlagSwitch React, you can:

Roll out features gradually – Control what percentage of users see a new feature.

A/B test different versions – Let users experience multiple UI variations without extra work.

Avoid breaking production – Instantly disable a buggy feature without redeploying.

Stay flexible – Override versions manually or let the system decide dynamically.

All of this happens automatically behind the scenes. No need to refactor your app, write complex logic, or set up a backend just for feature management.

Flexible Yet Stupidly Simple

Need global settings? No problem. You can tweak FlagSwitch React to work exactly the way you want:

const loadFeatures = flagSwitch({
  features: JSON.parse(import.meta.env.VITE_FEATURES),
  // Other global options can be defined here.
});
Enter fullscreen mode Exit fullscreen mode

Or if you just want to force a feature for testing, that’s just one line:

loadFeatures({ version: "single-step-checkout" });
Enter fullscreen mode Exit fullscreen mode

Feature Flags Are No Longer Just for Big Tech

For too long, feature flags and A/B testing have been seen as tools reserved for large enterprises with dedicated DevOps teams. But that’s changing. With FlagSwitch React, you get all the power of feature flags with none of the complexity.

No more conditional logic. No more painful rollouts. No more guessing what works.

Just import, define, and deploy—it’s that easy.
