Design System Components

When building components, the NEAR VM provides a complete set of Radix primitives to simplify UI development.

Radix UI

Using embedded Radix primitives on the NEAR VM is simple and straight-forward. You don't need to import any files:

return (
    <Label.Root className="LabelRoot">
      Hello World!
    </Label.Root>
);

Limitations

Currently, NEAR VM impose some limitations on the Radix UI framework:

• Form component is not available.
• You can't use .Portal definitions.
• Using CSS is different. You'll have to use a styled.div wrapper.

Using CSS

Here is an example on how to use CSS through the styled.div wrapper:

const Wrapper = styled.div`
  .SwitchRoot {
    ...
  }
  .SwitchThumb {
    ...
  }
`;

return (
  <Wrapper>
    <Switch.Root className="SwitchRoot">
      <Switch.Thumb className="SwitchThumb" />
    </Switch.Root>
  </Wrapper>
);

Using Wrapper

Using styled-components

You can use styled-components in combination with Radix UI primitives. Here's an example:

const SwitchRoot = styled("Switch.Root")`
  all: unset;
  display: block;
  width: 42px;
  height: 25px;
  background-color: var(--blackA9);
  border-radius: 9999px;
  position: relative;
  box-shadow: 0 2px 10px var(--blackA7);

  &[data-state="checked"] {
    background-color: black;
  }
`;

const SwitchThumb = styled("Switch.Thumb")`
  all: unset;
  display: block;
  width: 21px;
  height: 21px;
  background-color: white;
  border-radius: 9999px;
  box-shadow: 0 2px 2px var(--blackA7);
  transition: transform 100ms;
  transform: translateX(2px);
  will-change: transform;

  &[data-state="checked"] {
    transform: translateX(19px);
  }
`;

return (
  <SwitchRoot>
    <SwitchThumb />
  </SwitchRoot>
);

Using styled components

Forward references

The NEAR VM re-implements React's forwardRef as ref="forwardedRef".

You can use ref="forwardedRef" to forward references through <Widget /> to support Radix's asChild property:

Dialog.jsx

<AlertDialog.Trigger asChild>
  <Widget
    src="near/widget/TestButton"
    props={{ label: "Click Me" }}
  />
</AlertDialog.Trigger>

TestButton.jsx

const Button = styled.button`
  background: #f00;
`;

return (
  <Button type="button" ref="forwardedRef">
    {props.label}: Forwarded
  </Button>
);
