How to test and develop AWS lambda functions locally with nodejs?

⚡️ Blog post and source code: https://www.undefinedapps.com/post/te... In this video we build a nodejs lambda function while running and testing it locally. The lambda function that gets arguments from query params, uses axios to download the html of a website, uses cherio to parse out the title of the page and then saves the html file to S3 and returns a json response back to the user. We write local tests for the function using mocha and sinon (to create stubs). The video also covers: creating and deploying lambda functions to AWS setting up an S3 bucket running the lambda function from a public url managing lambda releases setting up github actions to deploy to AWS on 'git push' 0:00 intro 0:31 explain & demo the function we're testing 1:40 create and run the lambda locally 3:54 create the lambda function on AWS + permissions 4:34 bundle & deploy our local code to AWS 6:21 create a public url to access our function 7:14 write the code to download the html and parse the title (using axios and cherio) 8:52 manage the release of our function 9:45 write tests using mocha and sinon 12:27 create a stub for axios.get() using sinon 15:25 write the code to save files to S3 (using aws-sdk) 12:27 create a stub for S3 17:25 create an S3 bucket on AWS + permissions 18:15 run the function in production 19:06 adjust the tests 19:42 create a GitHub action 21:27 deploy to aws on every 'git push' 22:58 use our new workflow 26:16 create integration e2e tests ⭐️ Subscribe for more content: https://newsletter.undefinedapps.com/ #aws #lambda #nodejs
