Features

• Cache Segmentation: Dynamically segment application cache and user's experience based on cookies, query parameters and device type.
• Customizable: Flexible configuration options to handle caching strategies for specific needs.
• Deployment: Deploy your NextJS application just with a few commands.
• Self-Hosted: Full control over infrastructure of your application.

Quick Start

Installation

npm install @dbbs/next-serverless-deployment
# or
yarn add @dbbs/next-serverless-deployment

Deployment

First of all need to bootstrap necessary components for AWS CDK:

@dbbs/next-serverless-deployment bootstrap

NOTE: this command should be called just once. It will call AWS CDK bootstrap to add ability to use cdk in your AWS account.

Then to deploy NextJS app run the following command:

@dbbs/next-serverless-deployment deploy --siteName my-awesome-app --stage development

This command is going to create all necessary AWS resources (if they do not exist yet), bundle NextJS application and upload all assets to AWS.

Cache config

Create next-serverless.config.js file in the root of your app. Config files allows you to specify cache behaviour of your application.

Default config:

/**
 * @type {import('next-serverless-deployment').CacheConfig}
 */
const config = {
  noCacheRoutes: [],
  cacheCookies: [],
  cacheQueries: [],
  enableDeviceSplit: false
}

module.exports = config

• noCacheRoutes: specify list of routes which are going to be ignored to be cached.
• cacheCookies: list of cookie names for cache fragmentation.
• cacheQueries: list of query names for cache fragmentation.
• enableDeviceSplit: flag to control cache fragmentation based on device type (desktop vs tablet vs mobile).

CLI

bootstrap

Creates all CDK resources for AWS account. This needs to be called just once for specific AWS region.

@dbbs/next-serverless-deployment bootstrap
