    My fiance left me about a month ago during the hardest time of my life. I let myself be sad for a day then decided I want to work on my purpose which is to become a front-end developer. So far I bought your HTML and CSS course which is phenomenal. Once done going to buy your JavaScript then react course. Thank you so much, you courses have helped through this dark time and I know there is a light at the end of the tunnel!

      Im so sorry man, but these things can happen. I hope you get through all right. Just remember, there are still people out there that love you.
      By the way, (At the moment) there are plenty of fish in the sea (not if we keep global warming up though) and you'll find the perfect match one day!
      I hope you make it through!

    Amazing video as usual, Brad. Your example server was concise and showed exactly what was needed to demo redis. And honestly, I didn't think to use middleware to check for the cached result and end the response early. That's a 200 IQ play. (I probably would have put the cache check in the same endpoint right before making the fetch call, which is clearly suboptimal.) Thanks for the video! I really learned quite a bit, and I've interviewed with some big companies that do use Redis so it is an important skill.

    Thanks Brad for the great intro to using Redis with Node. I noticed small typo at 5:28 - it should have been something like process.env.REDIS_PORT || 6379 and not process.env.PORT || 6379. Wanted to document here as a comment for welfare of anyone setting up a PORT environment variable only and wondering why the script wouldn't run.
    EDIT
    -------
    Also app.listen( PORT, ... ) would be required.

    FYI if you're getting the node-fetch ES Module error its because newer node-fetch only supports import. You can either downgrade node-fetch to 2.6.1 to use require() or add "type": "module" to the package.json and use 'import' (for everything) instead of 'require'

    • @ShivaKumar-st9ps
      @ShivaKumar-st9ps 2 года назад

      You may not needed node-fetch anymore.
      In the latest version of Node.js (18.0.0), global fetch (experimental) is enabled by default.
