Transcript

- [Teacher] If you want to find links to meet, the a tag isn't gonna work for us. The link component generally replaces the anchor tag, wherever you want to create a hyperlink in your application. The href attribute should be replaced with the to attribute. And this can be either a string, an object, or a function. If you use an object, it could have any of these four properties defined pathname, search, hash, and state. If you use a function, the current location is passed to the function as an argument, and the function should return a location. Which could be a string or an object. Other properties a link component could have are, replace, which is a Boolean that when true means clicking the link replaces the current entry in the history instead of appending to it. innerRef, this is a function and it's there for legacy purposes. And others such as title, ID, class name, and any other props you'd like to be on the rendered anchor tag. However, it's often better from a stylistic point of view to use a special version of the component called NavLink. This add styling attributes to the rendered element, when the URL is matched. Those attributes are activeClassName. This is a string for the CSS class name to be added to the element when it is active. activeStyle is just an object that defines a number of styles to add to the element when it's active. If you supply exact, the active style will only be applied if this is set to true and the location is much exactly. Strict is another Boolean that defines if a match should be made if there is a trailing slash on the location. isActive, is a function to add extra logic to determine if a link is actually active. It's used to calculate if more than the links path name matches the current URLs path name. Location is an object which can be used to compare a different location than when using isActive. An aria-current allows you to set a string value to page, step, location, date, time or true. Look in the documentation for what they mean.
