#React router dom location code

Note: This guide only covers routing however, the aspect of creating a schema on Hygraph and how we consumed the data will not be covered notwithstanding, here is a link to the source code on GitHub, and I have also included a picture of what the schema looks like in this article. All aspects of routing covered in this guide are used in this application, which can be accessed via this live link. We would create/use a cocktails app that retrieves her data from Hygraph via GraphQL. To fully comprehend and follow this guide, we would create an application that properly illustrates almost all aspects of navigation with appropriate use cases. In React routing, you'll be using an external library called React router, which can be difficult to configure if you don't understand how it works. Routing is the process of redirecting a user to different pages based on their action or request. One of the most important features we always want to implement when developing these applications is routing. Then from the receiving component you can conditionally render markup based on the location state.React is an open-source front-end JavaScript library that allows developers to create user interfaces using UI components and single-page applications. Through client-side routing in Gatsby you can provide a location object instead of strings, which are helpful in a number of situations:Įxample of providing state to a link component Note that the path starts with a slash siteURL must therefore not end in one. Once you have added siteURL, you can form the absolute URL of the current page by retrieving siteURL and concatenating it with the current path from location. You can add this as a siteURL property on siteMetadata in gatsby-config.js. In this case, you would first need to add configuration that describes where your site is deployed. For example, you may want to add a canonical URL to the page header. Sometimes you need the absolute URL of the current page (including the host name) while using server-side rendering. This includes href for the absolute URL of the page, including the domain. In this case, all the information your browser exposes as window.location is available.

Running client side is the exception to this rule. The location object’s properties generally do not include the domain of your site, since Gatsby doesn’t know where you will deploy it. HashHistory in is used to track browser history with JavaScript when using hashrouter instead of browserrouter which uses the newer HTML5 history API.

#React router dom location update

Using hash in JavaScript is one way to update the browser URL and the DOM without having the browser do a full HTML page reload. Note that you have to parse the search field (the query string) into individual keys and values yourself. The location object is never mutated but makes it helpful to determine when navigation happens. Because Gatsby uses for client-side routing, the location prop is passed to any page component and represents where the app is currently, where you’d like it to go, and other helpful information.

Sometimes it can be helpful to know exactly what your app’s browser URL is at any given stage.
