Hi there,
Thanks @knowler for the great tutorial. It looks like a nice way to develop Sage themes, I’m really motivated to make it work completely!
When running :
lando yarn start
…I experience the same issue as @wbiggs: http://localhost:3000 isn’t working (connection refused).
Note: it’s the same for http://localhost:3001.
Thanks to @Olaf_Siebert’s comment, I’ve managed to make it work locally (running yarn start instead of lando yarn start). But it seems that this is not the right approach. Could you please tell me why? I probably don’t grasp the big picture of containers with WordPress theme development.
Finally, I think I miss some debug skills with containers. Why aren’t ports 3000 and 3001 correctly forwarded?
Here are the files I use and the outputs:
.lando.yml :
name: my-app
recipe: wordpress
proxy:
theme:
- localhost:3000
config:
php: '7.3'
via: nginx
webroot: web
database: mariadb:10.3
xdebug: true
# Add the following if you plan to use Sage as a starter theme
services:
theme:
type: node
overrides:
ports:
- 3000:3000
- 3000:3001
tooling:
yarn:
service: theme
Then when running lando start, everything looks fine:
$ lando start
Let's get this party started! Starting app..

BOOMSHAKALAKA!!!
Your app has started up correctly.
Here are some vitals:
NAME my-app
LOCATION /Users/yaaax/workspace/my-app
SERVICES appserver_nginx, appserver, database, theme
APPSERVER_NGINX URLS https://localhost:32901
http://localhost:32902
http://my-app.lndo.site
https://my-app.lndo.site
THEME URLS http://localhost
https://localhost
–> http://my-app.lndo.site displays the website 
web/app/themes/my-theme/resources/assets/config.json :
{
"open": false,
"entry": {
"main": [
"./scripts/main.js",
"./styles/main.scss"
],
"customizer": [
"./scripts/customizer.js"
]
},
"publicPath": "/app/themes/my-theme",
"devUrl": "http://appserver_nginx.my-app.internal",
"proxyUrl": "http://localhost:3000",
"cacheBusting": "[name]_[hash:8]",
"watch": [
"app/**/*.php",
"config/**/*.php",
"resources/views/**/*.php"
]
}
And when I run lando yarn start (from web/app/themes/my-theme/), again it looks fine:
$ lando yarn start
yarn run v1.16.0
$ webpack --hide-modules --watch --config resources/assets/build/webpack.config.js

But not change when refreshing my page on my browser (http://my-app.lndo.site), even after a refresh (and disabling cache)
it seems to work but I don’t fully understand what I’m doing here!
