React is a JavaScript library for building user interfaces. Learn what React is all about on our homepage or in the tutorial. React has been designed from the start for gradual adoption, and you can use as little or as much React as you need. Whether you want to get a taste of React, add some interactivity to a simple HTML page, or start a complex React-powered app, the links in this section will help you get started.

If you prefer to use your own text editor, you can also download this HTML fileedit it, and open it from the local filesystem in your browser. You can then either gradually expand its presence, or keep it contained to a few dynamic widgets.

It only takes a minute to set up! As your application grows, you might want to consider a more integrated setup. There are several JavaScript toolchains we recommend for larger applications. Each of them can work with little to no configuration and lets you take full advantage of the rich React ecosystem.

Learn how. People come to React from different backgrounds and with different learning styles. Like any unfamiliar technology, React does have a learning curve. With practice and some patience, you will get the hang of it. The React homepage contains a few small React examples with a live editor. It introduces the most important React concepts in a detailed, beginner-friendly way.

React D3 Library also supports transitions, animations, tooltips, zoom, brush, event listeners, and the list goes on. It's a simple process to create D3 elements in React and because of this we are able to make contributing or using templates easy. React-D3-Library will compile your code into React components, and it also comes with a series of D3 template charts converted to React components for developers who are unfamiliar with D3. Not only do we build fully functional React components, but they utilize the power of D3 to automate scaling ranges, normalizing data, and constructing legends.

We change the selection from d3. Use the componentDidMount React lifecycle method to make the state aware of your new D3 div.

Socializing with co-workers while social distancing.Portals provide a first-class way to render children into a DOM node that exists outside the DOM hierarchy of the parent component. The first argument child is any renderable React childsuch as an element, string, or fragment.

The second argument container is a DOM element. For example, dialogs, hovercards, and tooltips. When working with portals, remember that managing keyboard focus becomes very important.

Try it on CodePen. Even though a portal can be anywhere in the DOM tree, it behaves like a normal React child in every other way. Features like context work exactly the same regardless of whether the child is a portal, as the portal still exists in the React tree regardless of position in the DOM tree.

Getting Started

This includes event bubbling. An event fired from inside a portal will propagate to ancestors in the containing React treeeven if those elements are not ancestors in the DOM tree. Assuming the following HTML structure:. A Parent component in app-root would be able to catch an uncaught, bubbling event from the sibling node modal-root. Catching an event bubbling up from a portal in a parent component allows the development of more flexible abstractions that are not inherently reliant on portals.

Images are supported but will likely require custom styling to work well. Align the contents as needed with utility classes. Loose text and links can be wrapped Navbar.

Text in order to correctly align it vertically. Theming the navbar has never been easier thanks to the combination of theming classes and background-color utilities. Then, customize with the bg prop or any custom css!

You can use Bootstrap's position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top scrolls with the page until it reaches the top, then stays there.

Also note that. Since these positioning needs are so common for Navbars, we've added convenience props for them. Use the expand prop as well as the Navbar. Toggle and Navbar. Collapse components to control when content collapses behind a button. Set the defaultExpanded prop to make the Navbar start expanded.

Set collapseOnSelect to make the Navbar collapse automatically when the user selects an item. You can also finely control the collapsing behavior by using the expanded and onToggle props. The breakpoint, below which, the Navbar will collapse. When true the Navbar will always be expanded regardless of screen size.

Create a fixed navbar along the top or bottom of the screen, that scrolls with the page. Note: If you are manually closing the navbar using this OnSelect prop, ensure that you are setting expanded to false and not toggling between true and false.

Position the navbar at the top or bottom of the viewport, but only after scrolling past it. The general visual variant a the Navbar. Use in combination with the bg prop, background-color utilities, or your own background styles.

That child is mounted to the nearest DOM element and rendered inside of it as a result. What if we want to render that child outside of the div somewhere else? That could be tricky because it breaks the convention that a component needs to render as a new element and follow a parent-child hierarchy. The parent wants to go where its child goes. They provide a way to render elements outside the DOM hierarchy so that elements are a little more portable.

It may not be a perfect analogy, but Portals are sort of like the pipes in Mario Bros. The cool thing about Portals? The first line of a React application will tell you that an App element is rendered on the document root using ReactDOM.

Like this. Same sort of thing with Portals. This div will serve as our target. We create a new div element in the constructor and set it as a value to this. When the Portal component mounts, this. When the component unmounts we want to remove the child to avoid any memory leakage. We will import this Portal component into another component where it gets used, which is the the div that contains the header and button in our example.

This is why we have this. This is a special ReactDOM method that accepts the children and the element we created. When the App loads, we want to display a text and a button — we can then toggle the button to either show or hide the Portal component. Since we want to toggle the Portal on and off, we need to make use of component state to manage the toggling.

The portal gets rendered when on is true; else we render nothing. When on is falsethe Portal component is not being rendered in the root, so the DOM looks like this. Modals are a perfect candidate for Portals. In fact, the React docs use it as the primary example for how Portals work:.

We can even insert data from an outside source into a modal. In this example, the App component lists users fetched from an API using axios. Hopefully this gives you a solid base understanding of Portals as far as what they are, what they do, and how to use them in a React application. The concept may seem trivial, but having the ability to move elements outside of the DOM hierarchy is a handy way to make components a little more extensible and re-usable… all of which points to the core benefits of using React in the first place.

React is the web's most popular framework, always topping the charts for JavaScript developers awareness, interest, and satisfaction. Not to mention so many jobs listing it as a requirement these days.The tooltip configuration is passed into the options.

The global options for the chart tooltips is defined in Chart. The titleAlignbodyAlign and footerAlign options define the horizontal position of the text lines with respect to the tooltip box. The following values are supported. Allows sorting of tooltip items. Must implement at minimum a function that can be passed to Array. This function can also accept a third parameter that is the data object passed to the chart.

Allows filtering of tooltip items. This function can also accept a second parameter that is the data object passed to the chart. The tooltip label configuration is nested below the tooltip configuration using the callbacks key. The tooltip has the following callbacks for providing text. For all functions, this will be the tooltip object created from the Chart.

Tooltip constructor. All functions are called with the same arguments: a tooltip item and the data object passed to the chart. All functions must return either a string or an array of strings. Arrays of strings are treated as multiple lines of text. The label callback can change the text that displays for a given data point. A common example to round data values; the following example rounds the data to two decimal places.

Custom tooltips allow you to hook into the tooltip rendering process so that you can render the tooltip in your own custom way. Generally this is used to create an HTML tooltip instead of an oncanvas one. You can enable custom tooltips in the global or chart configuration like so:. See samples for examples on how to get started with custom tooltips.

Tooltips Tooltip Configuration The tooltip configuration is passed into the options. Name Type Default Description enabled boolean true Are on-canvas tooltips enabled?
