People create links and bookmark URLs. Content, for a variety of reasons, has to move from one place to another. For everyone's sake, you don't want to break the URLs that people have come to rely on.
You need to setup some redirects.
Though a Next.js app is just frontend code, when distributed through Vercel, you can include some configuration of the web server layer.
Add the vercel.json file to the top-level directory of your Next.js project
and then include any needed redirect rules.
{
"redirects": [
{
"source": "blog/old-blog-post-name",
"destination": "blog/new-blog-post-name"
},
{
"source": "/store",
"destination": "store.example.com"
}
]
}In the first rule, one path is redirected to another for the same domain. In the second rule, the path is redirected to an external URL.
By default, these redirects get a 308 status code.
