Vue routing

For single page applications, it is recommended to use the vue router. The router maps urls to vue components, so if you access a page like / it will load e.g. a homepage component, while /users will load the user list component.


If you are not familiar with vue router, please read to docs first, before you go on reading.

Only HTML5 mode

Here we discuss only the HTML5 history mode, because here the url behave like a normal web page and we need some integrations for symfony. For hash or memory mode we recommend do all work in javascript files, since normally we don't have further impacts to symfony.

Define vue routes

First of all, you have to define the routes for vue. The best place for the definition file is under the assets directory, e.g. assets/theme/vue_routes.json.

Here is a simple example for named and nested routes.

  { "path": "/dashboard", "name": "app_dashboard_index", "component": "dashboard-index" },
  { "path": "/people", "name": "app_people_index", "component": "people-index", "children": [
    {"path": "/people/user", "name": "app_people_user", "component": "people-user-index"}

Why do we need to define the routes in such a format instead defining it in a js file like it is mentioned in the vue router docs? Good question! Our goal is to have a single place for all vue routes. In HTML5 mode, the url will change in the browser if you move to a different route. That works fine in the browser, but if you reload, the http request arrives first in symfony and has no clue what to do with this url and may return a 404 not found page. So it's necessary to introduce the urls also to symfony. That's why we created a simple format for defining the routes and load it into the browser and in symfony.

Load routes into the browser

To push your defined routes to the browser, first you need to load the file into the vue route provider. The groups option is optional and can be used to only load several routes later on.

                type: file
                path: assets/theme/vue_routes.json
                groups: ['theme']


We recommend to use groups with area names, because normally they need to loaded only in a specific area.

Now, you can use the vue_routes options in app or area endpoint to pass the data to the frontend. With a string or array you can select which group will be loaded. A boolean true will load all routes, while false or null won't load any.

    path: /
            type: area
            vue_routes: ['theme'] 
            template: theme/base.html.twig

Load routes into symfony

To make the url available in symfony, you use the vue route loader (which is also a route). All routes will use the same endpoint, that is defined here.

# config/routes/vue.yaml
    resource: ../../assets/theme/vue_routes.json
    prefix: /
    type: vue
            type: area
            area: theme
            routes: ['theme', 'api']
            vue_routes: ['theme']
            template: theme/base.html.twig

If multiple endpoints are needed, you have to split your routes in separated files and load them separately.
