with-zones

Using multiple zones

With Next.js you can use multiple apps as a single app using it's multi-zones feature. This is an example showing how to use it.

In this example, we've two apps: 'home' and 'blog'. We also have a set of rules defined in rules.json for the proxy.

Now let's start two of our app using:

npm run home
npm run blog

Then start the proxy:

npm run proxy

Now you can visit http://localhost:9000 and access and develop both apps a single app.

Proxy Rules

This is the place we define rules for our proxy. Here are the rules(in rules.json) available for this app:

{
  "rules": [
    {"pathname": "/blog", "method":["GET", "POST", "OPTIONS"], "dest": "http://localhost:5000"},
    {"pathname": "/**", "dest": "http://localhost:4000"}
  ]
}

These rules are based on ZEIT now path alias rules and use micro-proxy as the proxy.

Special Notes

• All pages should be unique across zones. A page with the same name should not exist in multiple zones. Otherwise, there'll be unexpected behaviour in client side navigation.
  • According to the above example, a page named blog should not be exist in the home zone.

Production Deployment

Here's how are going to deploy this application into production.

• Open the now.json file in both blog and home directories and change the aliases as you wish.
• Then update rules-prod.json accordingly.
• Now deploy both apps:

cd home
now && now alias
cd ../blog
now && now alias
cd ..

• Finally, set the path alias rules with

now alias with-zones.now.sh -r rules-prod.json

You can use a domain name of your choice in the above command instead of with-zones.now.sh.

That's it. Now you can access the final app via: https://with-zones.now.sh
