Welcome to CDK DynamoDB Search

This is an Amazon DynamoDB helper written in TypeScript enabling full text search using Meilisearch on top of Amazon Web Services Cloud Development Kit (AWS CDK)

How does it work?

This package is a wrapper around Amazon DynamoDB table that listens to its ("INSERT", "MODIFY", "REMOVE") events using Amazon DynamoDB Streams.

Insert event

When an item/items is inserted in the table, an "INSERT" event is triggered, an AWS Lambda function listens to this event and inserts a document/documents based on the received record/records using Meilisearch Client add documents.

Modify event

When an item/items is inserted in the table, an "MODIFY" event is triggered, an AWS Lambda function listens to this event and updates a document/documents based on the received record/records using Meilisearch Client update documents.

Remove event

When an item/items is inserted in the table, an "REMOVE" event is triggered, an AWS Lambda function listens to this event and deletes a document/documents based on the received record/records primary keys using Meilisearch Client delete documents.

Modes

Currently the package supports two modes Cloud and Self-hosted:

Cloud

Uses Meilisearch Cloud service managed by Meilisearch team. You can check out Meilsearch Cloud pricing to get started on using the Meilisearch Cloud mode jump to Getting started with Meilisearch Cloud mode section

Self-hosted

Uses the official Docker image from Docker Hub hosted in AWS Fargate behind an AWS Application Load Balancer. You can calculate the cost here to get started on using the Meilisearch Cloud mode jump to Getting started with Meilisearch Hosted mode section

Getting started

Getting started with Meilisearch Cloud mode - View example

1. Install the package

• Using NPM npm install cdk-dynamodb-search
• Using Yarn yarn add cdk-dynamodb-search

2. Get the host and the API key Create an account in Meilisearch Cloud and get the host URL and the API key from your settings.

3. Import the package Import "WithCloudSearch" into the stack containing the table definition - Required

import { WithCloudSearch } from "cdk-dynamodb-search";

4. Wrap your DynamoDB table with the WithSearch helper - Required

new WithCloudSearch(this,"MySearch", {
	// my_table: dynamodb.Table - Required
	table: my_table  // Add here!!!
});

5. Add the search API key (will be used as the Meilisearch master key - Required

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    // apiKey: string - Required	
    apiKey: "MY_SUPER_SECRET_KEY" // Add here!!!
  }
});

6. Add the search host URL - Required

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    apiKey: "MY_SUPER_SECRET_KEY"
  },
  provider: {
    // host: string - Required
    host: "https://...your-meilisearch-host" // Add here!!!
  }
});

7. Deploy the solution - Required npx cdk deploy

That's it that was the minimal usage.

Create an item in your table and visit the host URL to see that item has been created successfully.

Further customization

If you want further customization you can customize the params:

1. Set the Meilisearch search index - Optional

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    apiKey: "MY_SUPER_SECRET_KEY",
    index: "my-search-index"
  },
  provider: {
    // host: string - Optional
    host: "https://...your-meilisearch-host" // Add here!!!
  }
});

Getting started with Meilisearch Hosted mode - View example

1. Install the package

• Using NPM npm install cdk-dynamodb-search
• Using Yarn yarn add cdk-dynamodb-search

2. Import the package Import "WithCloudSearch" into the stack containing the table definition - Required

import { WithHostedSearch } from "cdk-dynamodb-search";

3. Wrap your DynamoDB table with the WithSearch helper - Required

new WithHostedSearch(this,"MySearch", {
  // my_table: dynamodb.Table - Required
  table: my_table  // Add here!!!
});

4. Add the search API key (will be used as the Meilisearch master key - Required

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    // apiKey: string - Required - Create your own key
    apiKey: "MY_SUPER_SECRET_KEY" // Add here!!!
  }
});

5. Deploy the solution - Required npx cdk deploy

That's it that was the minimal usage.

Create an item in your table and visit the host URL to see that item has been created successfully.

Further customization

If you want further customization you can customize the params:

1. Set the Meilisearch search index - Optional

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    apiKey: "MY_SUPER_SECRET_KEY",
    index: "my-search-index"
  },
  provider: {
    // host: string - Optional
    host: "https://...your-meilisearch-host" // Add here!!!
  }
});

2. Set the container CPU compute power - Optional

• Import ComputeValue

import { 
  WithHostedSearch 
  ComputeValue // Add here!!!
} from "cdk-dynamodb-search";

• Add the container CPU compute power

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    apiKey: "MY_SUPER_SECRET_KEY",
    index: "my-search-index"
  },
  // container: WithSearchProps["ContainerProps"] - Optional
  container: {
    // cpu: ComputeValue - Optional - default 256
    cpu: ComputeValue.v512 // Add here!!!
  }
});

2. Set the container memory in megabytes - Optional

• Import ComputeValue

import { 
  WithHostedSearch 
  ComputeValue // Add here!!!
} from "cdk-dynamodb-search";

• Add the container memory

new WithCloudSearch(this,"MySearch", {
  table: my_table,
  search: {
    apiKey: "MY_SUPER_SECRET_KEY",
    index: "my-search-index"
  },
  // container: WithSearchProps["ContainerProps"] - Optional
  container: {
    // memory: ComputeValue - Optional - default 512
    memory: ComputeValue.v1024 // Add here!!!
  }
});
