#learned

• heroku doesnt use dev dependancies. we can switch our environent to add dev modules.
• added env files in heroku. works with app now.
• connecting with redis in the heroku server and getting / setting data.
• svelteJs setup
• added mocha and jest unit testing.

to do

we can run svelteJs from the command npm run build or npm run start. the problem is i need to run both node and then load sveltejs through the command. Now,

• how do i build the sveltejs app so that i can run it straight through clicking index.html - instead of needing to use a command to build the static app.
• its only the paths that need to be built.

==============

• unit testing with github and actions before pushing to heroku.

  • add unit testing and github workflow with git actions used before pushing updates

• redis

  • accessing redis from other files. so exporting the redis variable?.
  • when setting data, how much data does this use on the server?.
    • the free server holds 5MB of data.

• svelteJs

  • load some data from db.
    • set to redis.
  • show data from db or redis and tell user what storage was used.
  • learn the fetch requests
  • learn components.

• try to point domain to the heroku app.

• add a basic svelteJs frontEnd

  • components
  • getting data from server
  • preparing for the production server.

• make sure the heroku push master doesnt look at other scripts. it should only run npm run start.

• before deploying app to heroku, the NODE_ENV needs to be set to production .

  • if heroku finds that NODE_ENV is set to anything else, it does not prune dev_dependancies .
  • By default NODE_ENV is set to production. If NODE_ENV is any other value, the pruning step will be skipped. not sure what this is but i dont want dev-dependancies in a production build anyway.

• set a custom error middleware for production or for development.

  • i could have a custom file that contains all dev middleware and app.use();

app

( svelteJs , heroku , redis , git actions , CI / CD ).

• host a redis db on heroku
• setup basic redis caching when querying a db.
• add unit testing to function and routes.
• setup git actions for CI-CS Devops.
• git work in seperate branch
• pull requesting
• git remote add upstream, fetch upstream , rebase upstream.
• setup svelteJs front end and hit api.
