Netlify Lambda

Everythings start with ...

 npm init

Install the npm package netlify-lambda

npm install netlify-lambda

Add some sripts on package.json file, to build and serve the localhost for local development.

...
  "scripts": {
    "lambda-serve": "netlify-lambda serve functions",
    "lambda-build": "netlify-lambda build functions"
  },
...

• After, create a netlify.toml file for the config on root of the project.

 touch netlify.toml

and write on it :

[build]
    functions = "lambda"

• Create a folder 📁 functions on root of the project

mkdir functions

• Add your js file on it, for exemple.

touch  functions/welcome.js

exemple:

// welcome.js

exports.handler = (event, context, callback) => {
  const { name, age, nat } = JSON.parse(event.body);

  callback(null, {
    statusCode: 200,
    body: JSON.stringify({
      data: `hello ${name}, you're ${age} from ${nat}`
    })
  });
};

launch your localhost by running

npm run lambda-serve

Test with Postman on Insomnia

on POST and URI http://localhost:9000/welcome like below

Welcome in the new univers of Function As Service (FASS).

If you need to push on production, create on your favorite git storage provider but works well with hub.

git add .
git commit -m 'intial commit'
git push origin master

Go to your netlify dashboard and deploy your repo. You will go a url ( exemple: https://wizardly-wozniak-123c2b.netlify.com )

Your endpoint will be on functions tabs of the project, and set as PROJECT_URL/.netlify/functions/NAME_OF_YOUR_FUNCTION

• Enjoy your first lambda on netlify
