Using webpack-dev-server and HMR
Using webpack-dev-server and HMR¶
While developing, instead of using
yarn encore dev --watch, you can use the
$ yarn encore dev-server
This serves the built assets from a new server at
http://localhost:8080 (it does
not actually write any files to disk). This means your
need to change to point to this.
If you’re using the
Twig shortcuts (or are processing your assets through entrypoints.json
in some other way), you’re done: the paths in your templates will automatically point
to the dev server.
You can also pass options to the
dev-server command: any options that are supported
by the normal webpack-dev-server. For example:
$ yarn encore dev-server --https --port 9000
This will start a server at
This Webpack server is independent from Symfony’s development web server and you need to run both separately.
Using dev-server inside a VM¶
If you’re using
dev-server from inside a virtual machine, then you’ll need
to bind to all IP addresses and allow any host to access the server:
$ ./node_modules/.bin/encore dev-server --host 0.0.0.0 --disable-host-check
You can now access the dev-server using the IP address to your virtual machine on port 8080 - e.g. http://192.168.1.1:8080.
