How can you detect if a website uses Vue by looking at the source code?

Detecting whether a website uses Vue.js involves identifying specific markers associated with Vue. Here’s a step-by-step guide on how to do it:

  1. Open the Page Source: Right-click on the webpage and select “View Page Source” or press Ctrl+U (Windows) or Cmd+Option+U (Mac) to open the page source code.
  2. Look for Vue.js in Scripts: Search for references to Vue.js in the source code. Use Ctrl+F (Windows) or Cmd+F (Mac) to open the search function and look for the following keywords:
    • vue.js: Look for script tags that include Vue.js. Example: <script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
    • vue.min.js: This is the minified version and is often used in production environments. Example: <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.min.js"></script>
  3. Check for Vue-Specific Class Attributes: Vue.js uses specific directives in HTML. Look for attributes that start with v-, which are used in Vue templates. Examples include:
    • v-bind:: Used to dynamically bind attributes. Example: <div v-bind:id="dynamicId"></div>
    • v-ifv-forv-model: These are common Vue directives. Example: <div v-if="isVisible">Visible Content</div>
  4. Look for Vue Instance Initialization: Search for JavaScript code that initializes a Vue instance. This often looks like: new Vue({ ... })
  5. Check for Vue Router or Vuex: If the site uses Vue Router for routing or Vuex for state management, you may find these references in JavaScript imports or in the source code:
    • vue-router: Look for script imports or initialization code related to routing.
    • vuex: Look for references related to state management using Vuex.
  6. Search for the Vue Devtools: If the site is using Vue.js, it may also include links to the Vue.js Devtools in its code. Look for: <!-- Vue.js devtools --><script src="https://cdn.jsdelivr.net/npm/vue-devtools"></script>
  7. Check for Data Binding Syntax: Vue.js uses a specific syntax for data binding, which often looks like this: {{ variableName }} in the HTML. Search for double curly braces in the HTML code.
  8. Examine Network Requests: Open your browser’s Developer Tools (usually F12 or right-click and select “Inspect”) and check the “Network” tab. Look for any loaded scripts or assets containing “vue” in their filenames or paths, as they may indicate Vue.js being used.
