Automatic injection of Vue router routes

Have you ever had your Vue router file get so big that it started getting messy to maintain?

How about if you had a separate JS file for each route that can be organized into folders and sub folders. And these files are auto injected into the Vue router.

Create a folder in your /src directory called /router and inside it create an index.js file and /routes directory

Inside the routes directory start creating files for each route you have in your app. You could also create these file in subdirectories inside the routes directory.

Routes directory with route files

Each file should have the below structure.

//this lazy loads the component
const ViewComponent = () => import("@/views/ViewOne");

export default {
    path: "/view-one",
    name: "View One",
    component: ViewComponent,
    show_in_menu: false,
    meta: {
        search: {
            enabled: false,
        },
    },
};

Enter fullscreen mode Exit fullscreen mode

As you can see each file would have the normal attributes you would normally find in a vue router config array.

Loading the view component is using an arrow function, the only difference is that using an arrow function lazy loads the component instead of loading it directly.

You might also find additional attributes, e.g:show_in_menu, search object in the meta.

I use these to auto configure routes based on these configurations. The show_in_menu value, if true, will inject this route into the side navigation menu. For the search, if enabled, it will show a search bar in the Toolbar.

Now once you add all your routes in different files, you need to update the index.js we previously created to the following:

import Vue from "vue";
import VueRouter from "vue-router";

Vue.use(VueRouter);

//automatically load all files from ./routes directory and register them
const autoLoadedFiles = require.context(
    "./routes", // Look for files in the current directory
    true, // include subdirectories
    /\.js$/ // Only include files that end with .js
);

const routes = [];
//loop over the files in the ./routes directory
autoLoadedFiles.keys().forEach((fileName) => {
    //get the default exported object from the route file and push it to the routes array
    routes.push(autoLoadedFiles(fileName).default);
});

const router = new VueRouter({
    base: '/base-url,
    routes,
});

export default router;
Enter fullscreen mode Exit fullscreen mode

And finally you need to import this file in your main.js or app.js file

import router from "./router";
Enter fullscreen mode Exit fullscreen mode

BONUS:

To retrieve the show_in_menu attribute you can loop over the routes as follows:

this.$router.options.routes.forEach((route) => {
    if (route.show_in_menu) {
        navItems.push(this.createNavItem(route));            
    }
});
Enter fullscreen mode Exit fullscreen mode

To retrieve the meta object you can do so as follows:

this.$router.currentRoute.meta
Enter fullscreen mode Exit fullscreen mode

Let me know what do you think of this solution in the comments and if this is something you might use in your projects.

Cheers!

Just kidding, it's a personal preference. But you can change your theme, font, etc. in your settings.
