I'm trying to use the sample code for an app bar provided in the documentation note that I'm not using the AppBar component- I have my own header component. But I'm currently trying to create a SearchField component based on this code. I've basically cut and pasted the code as-is, and pulled out the parts not related to the search field.
Digging into it, I see that the theme object being passed into the function I pass into makeStyles is an empty object. I investigated further, to see if I could get my hands on the theme. When I export my component with withTheme searchBarthe theme object in the props is null.
Likewise, if I just call useTheme in my component, it also returns null. Note: it seems the plain JS sample code no hooks works - so this has something to do with the Material-UI and React However- this version is required to use the sample hooks code.
My makeStyles function should be passed the populated theme object, and withTheme and useTheme should return the proper non-null theme object. The theme object passed into makeStyles is empty. The theme props attribute injected by withTheme is null. The theme object returned by useTheme is null.
This is exactly the type of frustration that working on v4 enable us to fix. I can think of the following possible approaches:.What I mean by this is they provide a whole bunch of different options of getting your job done. For example, basically, you are given 3 different ways to style your components. Multiple options guarantee you will always find the most appropriate way to style your components with ease. In this post, I am not gonna discuss where and how you should use each of these apis but walk you through the process for component styling.
The above screenshots show how an outlined textfield look like when being rendered in different states — initial state and focused. Now make some changes to its styles:. Well, the answer is yes and no. For some simple components that does not have much constitutional React elements we can use className. For TextField in our example, className will not help. Let me show you what happens when using className. Why is that?ReactJS Tutorial - 20 - Styling and CSS Basics
It rings the bell!! Looking at OutlinedInput docs, it has a quite number of class names that allow you to control its styling. Question here is which class should we look at? To work this out, my trick is hover through DOMs as shown in the above screenshot until you see any highlighted DOM exactly covers the text field.
Now, it becomes more clear that we need to overwrite styles in root class. However, we will see two borders overlapping each other if we do this:. Now, it points us to fieldset and we need to find a way to overwrite border-color value:. A translation from css to jss mui flavor is like this:. If we now hover over the text field, border colour finally becomes red. Mission one completed! Likewise, we can follow the same path to get this mission done easily.
Tip: If you get annoyed by losing focus on input when you click your mouse elsewhere than input itself, you can simply remove blur event from event lists displayed under Event Listeners tab. I understand it can be a tough time for beginners to get styling with material-ui right and hope this post can help them conquer it. Sign in.Material-UI aims to provide a strong foundation for building dynamic UIs. You can use it, but you don't have to, since Material-UI is also interoperable with all the other major styling solutions.
In previous versions, Material-UI has used LESS, then a custom inline-style solution to write the component styles, but these approaches have proven to be limited. A CSS-in-JS solution overcomes many of those limitations, and unlocks many great features theme nesting, dynamic styles, self-support, etc. Material-UI's styling solution is inspired by many other styling libraries such as styled-components and emotion.
There are 3 possible APIs you can use to generate and apply styles, however they all share the same underlying logic. Note: this only applies to the calling syntax — style definitions still use a JSS object. You can also change this behaviorwith some limitations. You can nest selectors to target elements inside the current class or component. This is green since it is inside the paragraph and this is blue since it is inside the span.
You can pass a function to makeStyles "interpolation" in order to adapt the generated value based on the component's props. The function can be provided at the style rule level, or at the CSS property level:. In the following stress test, you can update the theme color and the background-color property live:. This solution is isolated. It doesn't have a default theme, and can be used to style React applications that are not using Material-UI components. To remove the need to systematically supply a theme, the default Material-UI theme is applied to the re-exported makeStylesstyledwithThemeuseThemeand withStyles modules.
Skip to content Material-UI v4. Diamond Sponsors. Basics Advanced API. Edit this page. Why use Material-UI's styling solution? To install and save in your package. Styled with Hook API.The implementation strategy here is different — instead of including a generated CSS file that applies to all of the elements, each component includes the CSS that it needs in an isolated way. This is done with webpack basically. Which actually makes a lot of sense…. The basic way that material-ui does styling is with the withStyles higher order component.
You can treat it as boilerplate code for now, but lets first get started rebuilding the same site as we did last time and seeing what looks like. First thing we do is to add material-ui next and our favorite WebFont loader. And then we load the Roboto font from the Google mothership.
The Material Icons will come in as part of the npm package above. Now lets build out the nav bar component. This is going to look at lot more complicated than the rmwc version! On the other hand, absolutely everything you need to understand what is going to be displayed is self-contained in this file.
Lets walk through all the differences. For example, on a mobile device. In that case will we show a full screen window. Let us now recreate the drawer. Now that we have the drawer in place, lets now build a simple little feed to start testing things on. And finally, lets update the App. And this should look familiar! Themes in material-ui are top level objects that get set using the MuiThemeProvider component.
This, in turn, will do some magic with the React context and the theme object will get passed into the function that you provided to withStyles. Lets have an example to see what I mean. Much like learning how to play an instrument, going back and repeating each section to learn it better makes the final performance that much easier. Material-UI has a lot more activity on the project than rmwc does. But if you are building in React, which we are, MaterialUI seems like a much more effective and powerful choice.

More From Medium.Complexity can be a significant barrier for developers considering a new technology. We are often pressed for time and we need to be confident that the learning curve is surmountable within a given time-frame to be worth the investment. Learning React can be daunting enough for someone new to the technology.
Discovering that there are various techniques that must be grasped in order to solve more complex problems can create a significant barrier. These techniques came about organically over time and developers who used React from the get-go have had time to absorb why these are necessary but they can cause difficulty for someone learning the latest incarnation from scratch. React Hooks are an exciting, non-breaking addition to React js that facilitate improved functional decomposition of components and re-use of code.
Custom hooks allow related slices of stateful components to be extracted into reusable libraries that can be elegantly imported into functional components.
This has major implications for the simplifying, testing, organization, sharing, and maintenance of potentially simpler, and more atomic code. React hooks are currently still under alpha, but will be added to version 16 of React js over the next few months as it will be a non-breaking change. And then change to the root of the newly created app and run:. These can be used directly or to create custom hooks.
These two are the bread and butter of hooks, and go together like a horse and carriage, Starsky and Hutch, Batman and Robin… you get the idea. The intention here is that, in future, there should be just one recommended, consistent way to create components. Functions are an obvious choice and using them with hooks has positive impacts on diagnostics and debugging, minification, lines of code, code reuse, and complexity reduction.
The following short React tutorial, should help readers learn some React hooks basics. The function will manage the Form field elements using custom hooks to manage state and events for modifying state and validation.
From your terminal install material-ui core and styles using the following commands. Note: to switch from the default style to this version, currently you must import install from this library, and execute it before importing other material-ui components.
Now the custom hook and TextField are linked together. The state and events are managed within the hook, and the object returned by the hook passes the state and handlers to the TextField object using the spread operator to pass in as props. The function for providing input state and functionality can be put in a library for future use and the logic is kept completely separate from the visual rendering and is managed in an intuitive way.
The custom hook can be reused then for multiple inputs if necessary e. Another advantage of this is that unit tests can be written effectively around the custom hook function, and the logic for handlers and state are managed in one place in a straightforward way.
In the code above, we pass in a reference to a callback function, which takes the value and a regular expression as arguments.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I will add that into the docs. It's not clear to me how But given how much people are asking for this feature. It's something I can prioritize, after the bug fixes. You can use the injectSheet HOC, but it's open the door to multiple issues: memory leak, hot reloading broken, no classes composition, no internal ref access, broken theme nesting handling. At least, it's some of the issues I have been facing in the past and motivated my rewrite.
I think that step by step those issues will be addressed. This would make it much easier to customize components. For example, I'd like to have a checkbox with a configurable size i. For now, do you have any recommendations about how we should approach these types of use cases?

Aldor Aldor 63 7 7 bronze badges. Active Oldest Votes. There is no problem in separating the styles from the components. I for one even import the makeStyles hook inside the styles. Sabbin Sabbin 1, 8 8 silver badges 20 20 bronze badges. Thanks, but can you tell me how should I use the makestyles in my component?
There are so many things that work differently in mui. Like if I wanna change the color of the text,how do I do it? They are the same CSS props but with camelCase not with dash, so background-color is backgroundColor and so on Okay,thanks a lot, but somehow makestyles isn't working for me, but making styled components in a separate file and exporting them from there, is working fine for me. Is this the best approach to override mui styles?
