This example shows how to use AWS Lambda deployed through Mantil with Mongo Atlas.

This example is created with Mantil. To download Mantil CLI on Mac or Linux use Homebrew

brew tap mantil-io/mantil
brew install mantil

or check direct download links.

To deploy this application you will need:

• AWS account
• Mongo Atlas Account

To locally create a new project from this example run:

mantil new app --from mongo-atlas
cd app

Before deploying your application you will need to create Mongo Atlas cluster. Detailed instructions on how to create a cluster can be found in documentation.

Once your cluster is created you need to add connection URI to config/environment.yml as env variable for your function. Instructions on how to get this URI can be found here.

project:
  env:
    CONNECTION_URI: # connection uri to mongo atlas

Note: If this is the first time you are using Mantil you will need to install Mantil Node on your AWS account. For detailed instructions please follow the setup guide

mantil aws install

After configuring the environment variable you can proceed with application deployment.

mantil deploy

This command will create a new stage for your project with default name development and deploy it to your node.

Now you can output the stage endpoint with mantil env -u. The API endpoint for your function will have the name of that function in the path, in our case that is $(mantil env -u)/db.

After deploying application you can start working with the mongo database.

What follows are invoke examples for creating, fetching and deleting items.

mantil invoke db/create -d '{"id":1,"name":"item"}'
mantil invoke db/get -d 1
mantil invoke db/delete -d 1

To remove the created stage with all resources from your AWS account destroy it with

mantil stage destroy development
