Vue Js Detect Internet Speed:Vue.js is a progressive JavaScript framework that allows developers to build user interfaces efficiently. To detect internet speed in Vue.js, we can use the built-in JavaScript object navigator.connection. This object provides valuable information about the network connection, including the type and speed of the network.
We can access the speed of the network by using the navigator.connection.downlink property. This property returns an estimate of the maximum downlink speed of the network in megabits per second (Mbps).
We can use this information to optimize the user interface of our Vue.js application, for example, by reducing the size of images or videos for slower network connections. This can help improve the user experience and reduce the load time of our application
How can Vue js detect the user internet speed?
This is a Vue.js code that detects the internet speed and displays a message based on the detected connection type. The code uses the navigator.connection API to get information about the user’s network connection.
The code first creates a Vue app with three data properties: isLoading, connectionType, and bandwidth. isLoading is initially set to true to show a loading message while the connection information is being fetched. connectionType and bandwidth are initially set to empty strings.
The mounted lifecycle hook is used to fetch the connection information using the navigator.connection API. If the API is supported by the user’s browser, the code waits for the ready promise to resolve before setting the connectionType and bandwidth properties based on the connection information. If the API is not supported, the code sets connectionType to 'Unknown' and bandwidth to 'N/A'.

The computed properties are used to determine the connection type based on the connectionType and bandwidth properties. If the connectionType is '4g' or '5g' or the bandwidth is greater than or equal to 10, the connection is considered fast. If the connectionType is '2g' or '3g' or the bandwidth is less than 1, the connection is considered slow.
