Data Persistence

Now is a serverless hosting where the workloads are static or stateless. The data is not stored permanently (only transient)

• Using Cloud APIs that can store metadata on your behalf.
  • store users in a authentication service
  • subscriptions on Stripe
  • content in strAPI
  • file system in S3 bucket
• Use Cloud Databases that offer secure (preferably HTTPS-based) gateways, for example:
  • Azure CosmosDB
  • MongoDB Atlas
  • Firebase
  • Google Cloud SQL
  • IBM (https://compose.io/)

Request handling

When ZEIT Now processes incoming requests at the network edge:

• It can return a static file directly
• It can return a cached response
• It can invoke a lambda that returns a dynamic response

now.json

Only files that are matched by the src property of a Build are “considered for serving”

• deployment - config file

{
  "version": 2,
  "name": "next-mysql",
  "alias": "next-mysql.now.sh",
  "builds": [
    { "src": "api/**/*.js", "use": "@now/node" },
    { "src": "next.config.js", "use": "@now/next" }
  ],
  "routes": [
    {
      "src": "/api/profiles/(?<id>[^/]*)",
      "dest": "api/profiles/profile.js?id=$id"
    }
  ],
  "env": {
    "MYSQL_HOST": "@mysql_host",
    "MYSQL_USER": "@mysql_user",
    "MYSQL_PASSWORD": "@mysql_password",
    "MYSQL_DATABASE": "@mysql_database"
  }
}

where:

• version ensures you are using the latest Now 2.0 platform version
• name defines a project name your deployment will be known by under Now
• alias allows you to set an alias for a production deployment
• builds instructs Now to use the @now/node and @now/next builders for your applications API and interface respectively
• routes routes individual profile requests to the correct function, with the id parameter
• env injects defined secrets into the app, exposing them as environment variables
