AWSLambda

AWS Lambda Functions

Dev

Under root directory, run

npm ci

Make sure your editor support eslint and prettier (maybe you'll need to add extensions for them). VS Code (https://code.visualstudio.com/) is suggested here as the editor.

Configure Visual Studio Code

1. Install Eslint and Prettier extensions

2. Update settings to make use of the extensions, and let Prettier auto-format the code based on the eslint config file. More specifically: In the top nav bar of VS Code, click Code -> Preferences -> Settings -> {} at the top right coner as shown below.

Update the settings as

{
  // Editor
  "explorer.confirmDelete": false,
  "explorer.confirmDragAndDrop": false,
  "window.openFilesInNewWindow": "on",
  "window.zoomLevel": 0,
  "editor.fontSize": 14,
  "files.autoSave": "onFocusChange",
  "editor.formatOnSave": true,
  // Use eslint config as the rules for prettier
  "javascript.format.enable": false, // disable default formatter
  "prettier.eslintIntegration": true
}

Then restart the vs code editor, you should see Prettier automatically format your code, whenver you save your file.

Deploy using Serverless

Prerequisites:

####Setup serverless module

First install serverless globally:

npm install -g serverless

####Setup AWS credentials Edit ~/.aws/credentials and ~/.aws/config files under directory. For windows users this is `C:\Users\USERNAME.aws'

credentials file:

[aquaNow-PROD]
aws_access_key_id=...
aws_secret_access_key=...

config file - configure profile name and cloudformation stack region

[aquaNow-PROD]
region=us-east-1

Start to deploy

When deploying the project, a stage variable is used to specify which environment (AWS Account) will the lambdas (as well as other infrastructures) be deployed to. Currently the available stage variables include: PROD, DEV.

Deploy the entire project:

sls deploy --stage PROD

Update a function - this is useful when you want to update and test a single lambda function:

sls deploy --stage PROD --function orderHistory

Miscellaneous

Create API Key for a user

const request = require("request");

const executeAPIUrl = 'https://execute.aquanow.io'; // Adjust your url accordingly

const options = {
  method: 'POST',
  url: `${executeAPIUrl}/apiKey`,
  headers:
   {
     'cache-control': 'no-cache',
     'Content-Type': 'application/json'
   },
  body: {
    userId: 'fuzionadmin', // required | username
    customerId: 'aquanow', // optional
  },
  json: true
};

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});

Run scripts in script folder

Make sure you have correct aws credentials configured on your terminal. You can check aws credentials using aws configure

npm run script scripts/addRfqExchange.js
