Ignite Built-in Components

Ignite comes with a number of customizable built-in React Native components -- sort of a lightweight design system, in a way. It's the system we (at Infinite Red) tend to use the most often with our own custom mobile designs, and is designed to emphasize flexibility and customizability over out-of-the-box power.

There are a number of other options out there that work great with Ignite -- UI Kitten, RN Elements, and more. But if you're building something with a totally custom design, Ignite's built-in components work great.

Components​

Custom Components​

Ignite includes a generator for creating custom components. If the built in components don't fit your needs, you can create your own.

npx ignite-cli generate component MyCustomButton

Running the generator will create a new component in the components directory.

-- app
  -- components
    -- MyCustomButton.tsx
