Jaypie Mongoose 🐦‍⬛🪿

MongoDB management for Jaypie

🐦‍⬛ Introduction

Jaypie is an opinionated approach to application development centered around JavaScript and the JSON:API specification in an event-driven architecture.

📋 Usage

@jaypie/mongoose is an optional package that should be installed alongside the main jaypie package.

Installation

npm install jaypie @jaypie/mongoose

Example

import { connectFromSecretEnv, disconnect, jaypieHandler, mongoose } from "jaypie";

export default jaypieHandler(
  // Handler function
  async (...args) => {

    // "Your Code Here"
    // Do something with `mongoose`?

    return json;
  },
  // Configuration (optional)
  {
    name: "myEventHandler",
    setup: [connectFromSecretEnv], // Array of setup functions
    teardown: [disconnect], // Array of teardown functions
  },
);

Example Caveats

• SECRET_MONGODB_URI environment variable containing AWS secret name and associated permissions described in connectFromSecretEnv prerequisites (below)
• Use expressHandler or lambdaHandler, not jaypieHandler directly

📖 Reference

const {
  connectFromSecretEnv,
  disconnect,
  mongoose,
} = require("@jaypie/mongoose");

connectFromSecretEnv

import { jaypieHandler } from "@jaypie/core";
import { connectFromSecretEnv } from "@jaypie/mongoose";

export default jaypieHandler(
  // Handler function
  async (...args) => {

    // "Your Code Here"
    // Do something with `mongoose`?
    // Don't forget to `mongoose.disconnect()` or better yet, pass `disconnect` to `teardown`

    return json;
  },
  // Configuration (optional)
  {
    name: "myEventHandler",
    setup: [connectFromSecretEnv],
  },
);

// This is a theoretical example. In practice you would use this as a handler lifecycle function
const mongoose = await connectFromSecretEnv();

Prerequisites

• An AWS secret. Ths can be deployed by CDK with new secretsManager.Secret
• The lambda function must have access to the secret. CDK mongoConnectionString.grantRead(expressLambda);
• The AWS lambda params and secrets layer. CDK lambda.ParamsAndSecretsLayerVersion.fromVersion
• The lambda function must have access to the secrets layer. CDK paramsAndSecrets: paramsAndSecretsLayer,
• The name of secret. Usually it is ugly like MongoConnectionString37D5BF-XUCja0vKbFwa. CDK mongoConnectionString.secretName
• This name stored in an environment variable, preferably SECRET_MONGODB_URI. CDK SECRET_MONGODB_URI: mongoConnectionString.secretName, in the lambda environment property

If this sounds like a lot to think about think about never thinking about it again 👺

disconnect

What it says on the tin. Literally:

return await mongoose.disconnect();

mongoose

The mongoose object

import { mongoose } from "@jaypie/mongoose";

// Honk!
