Reason bindings for material-ui

This library provides Reason bindings for material-ui. It's automatically generated by reason-mui-binding-generator.

These bindings are mostly complete, just a few more indepth use cases (Theming etc.) are missing. I use them in production daily by now, still, if you encounter any problems please feel free to open an issue

Installation (for your Reason project)

Run:

yarn add @jsiebern/bs-material-ui

to add the library to your project dependencies. And add @jsiebern/bs-material-ui to the bs-dependencies node of your bsconfig.json.

Installation of the withStyles code extension (ppx)

Add the entry ./node_modules/@jsiebern/bs-material-ui/ppx_withStyles to the ppx-flags node of your bsconfig.json.

Example

Please see the examples folder.

withStyles

In material-ui, the withStyles HOC takes care of turning React styles into CSS via react-jss. It passes a classes prop onto the component with the first level keys of the style object passed on.

HOC do not translate well into Reason which is why we are using a render prop to make things easier. (More information on the topic).

withStyles Example PPX (typesafe)

Make sure you have implemented the ppx file (see installation for reference)

The code extension allows you to write a typesafe styled component with ease. It follows the format [%mui.withStyles "ComponentName"({ className: ReactDOMRe.Style.t })]. The generated Component has a render function which passes on a record with the class keys. See the example below.

let component = ReasonReact.statelessComponent("Example");

[%mui.withStyles
  "StyledExample"({
    alignRight:
      ReactDOMRe.Style.make(~width="100%", ~textAlign="right", ()),
  })
];

let make = _children => {
  ...component,
  render: _self =>
    <StyledExample
      render={
        classes =>
          <div className={classes.alignRight}>
            "Example text - aligned to the right"->ReasonReact.string
          </div>
      }
    />,
};

withStyles Example (unsafe)

You need to pass a classes prop of type list( { name: string, styles: ReactDOMRe.Style.t } ) and a render function to the component. See the following example:

let component = ReasonReact.statelessComponent("Example");

let make = _children => {
  ...component,
  render: _self =>
    <MaterialUi.WithStyles
      classes=[
        {
          name: "alignRight",
          styles:
            ReactDOMRe.Style.make(~width="100%", ~textAlign="right", ()),
        },
      ]
      render={
        classes =>
          <div className=classes##alignRight>
            "Example text - aligned to the right"->ReasonReact.string
          </div>
      }
    />,
};

Colors

All Colors are accessible in Submodules of the Module Colors. Color keys that are a pure number begin with a c. (MUI Docs Reference).

Example:

[%mui.withStyles
  "ColorExample"({
    bgColor: ReactDOMRe.Style.make(~backgroundColor=MaterialUi.Colors.Red.c300, ())
  })
];

Overriding with classes

To take advantage of Reasons type system when overriding classes directly on components they have been converted into Variants and need to be passed as a list to the components classes prop. It is best used in combination with the MaterialUi.WithStyles component.

(MUI Docs Reference).

Example:

let component = ReasonReact.statelessComponent("Example");

[%mui.withStyles
  "OverrideExample"({
    fontSize: ReactDOMRe.Style.make(~fontSize="30px", ()),
    bgColor:
      ReactDOMRe.Style.make(
        ~backgroundColor=MaterialUi.Colors.Red.c300,
        (),
      ),
  })
];

let make = _children => {
  ...component,
  render: _self =>
    <OverrideExample
      render={
        classes =>
          <MaterialUi.Button
            color=`Primary
            variant=`Raised
            classes=[
              Root(classes.fontSize),
              RaisedPrimary(classes.bgColor),
            ]>
            "Example Button"
          </MaterialUi.Button>
      }
    />,
};
