来自带有symfony 4的socket / io的webpack / encore

Question

I tried to use socket.io in my symfony 4 project, still I encounter some issues. I used npm install --save socket.io

then i get this :

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

+ socket.io@2.1.1
added 101 packages in 9.519s

But i was thinking "it's ok, it just notice me and it look optionnal".

Still when i used webpack/encore i get :

PS C:\wamp64\www\PROJETS\my-projet> ./node_modules/.bin/encore dev
Running webpack ...

 ERROR  Failed to compile with 2 errors                                                                         15:41:22

These dependencies were not found:

* fs in ./node_modules/socket.io/lib/index.js
* uws in ./node_modules/engine.io/lib/server.js

To install them, you can run: npm install --save fs uws

But install what they want ( fs uws ) don't make it work better when i use webpack/encore ... What should i do ?

Answer 1

socket.io is a server side node.js package, you are not supposed to run using webpack. Maybe you are looking for socket.io-client ? Otherwise, you should use a separate node.js environment.

Answer 2

It works, client side can be compiled now. I used import io from 'socket.io-client'; .

Server side i did it by this way : let io = require('socket.io')(server); .

But i'm thinking (server side) that for deployement webpack/encore will not compile libraries, then should i add them in sub folder of my Server App ?

Something like this :

Symfony 4 project | assets | bin | config | server_app | | server_app.js | | lib | | | here lib for socket.io | public | src | template ...

(my question may seem stupide) if I wont add all node_modules folder on my server, should I copy paste socket.io's folder from node_modules to the new folder " lib " indicated above ? (all or part)

Else is it a wrong way to deploy it ? (sorry, i'm not familiar with it, I normaly only upload the compiled file from Encore ... then when I need to deploy a server side app ...)
