Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Development Instructions

Set up

  • brew install node (or brew equivalent)

  • brew install heroku/brew/heroku

  • heroku login

  • optional but helpful: heroku autocomplete (and follow instructions)

  • setup staging and production remote, run these commands in this order

    1. heroku git:remote -a replicache-license-staging
    2. git remote rename heroku staging
    3. heroku git:remote -a replicache-license
  • verify your remotes are correct

    git remote -v

    output should look like this:

    heroku  https://git.heroku.com/replicache-license.git (fetch)
    heroku  https://git.heroku.com/replicache-license.git (push)
    origin  [email protected]:rocicorp/licensing.git (fetch)
    origin  [email protected]:rocicorp/licensing.git (push)
    staging https://git.heroku.com/replicache-license-staging.git (fetch)
    staging https://git.heroku.com/replicache-license-staging.git (push)
  • install Docker, run it, and configure Settings to start when you log in (if you'd like)

  • install postgres (for the psql cli, we use docker to actually run postgres) eg brew install postgresql

  • create a .env file in the root directory of the project with contents:

    DATABASE_URL="postgresql://testuser:testpw@localhost:5433/test"

    Note: currently the same db is used by tests and when you run the server locally. It's wiped each start/test but still, that's lame. See note in docker-compose.yml and feel free to fix this.

Common tasks

  • IMPORTANT: npm run start is for production. The prod db is persistently running so doesn't need to be started. When running locally we need to start a local, dockerized db; use npm run start_local to start up locally.

Database

  • connect to local db:
    • npm run start_test_db
    • npx prisma migrate dev
    • source ./.env && psql $DATABASE_URL
  • generate a migration:
    • npx prisma migrate dev --name foo generates the new migration
    • npx prisma generate generates the new client
  • dev migration compaction: to compact several new, locally applied migrations (do not do this in production, or if they have been applied in prod, unless you are resetting the prod db, which you probably should not be)
    1. bring up the local db eg npm run start_test_db && npm run migrate_test_db
    2. remove the migration rows in the db from the _prisma_migrations table
    3. remove the migration dirs from primsa/migrations
    4. run npx prisma migrate dev which will generate a new migration AND RESET THE LOCAL DB
  • BACKUPS
    • automatic physical backups happen continuously and are saved for a week and can be restored using rollbacks
    • logical backups happen every 24h at 2am pacific time and are kept for ~30 days (heroku pg:backups:schedule --at '02:00 America/Los_Angeles' --app replicache-license)
    • capture a manual logical backup:
      • heroku pg:backups:capture --app replicache-license
    • list logical backups:
      • heroku pg:backups --app replicache-license
    • restore from a logical backup:
      • heroku pg:backups:restore <backupid eg b001> --app replicache-license

Environments

We have two environments:

  1. staging: app replicache-license-staging remote name 'staging'
  2. production: app replicache-license remote name 'heroku'

Env vars, resources, etc. are NOT automatically reflected from prod to staging, you need to remember to add them both places eg:

heroku config:set --a replicache-license-staging FOO=bar
heroku config:set --a replicache-license FOO=bar

Pushing code

  • to push from main: git push heroku main or git push staging main
  • to push from someother branch: git push <heroku|staging> someother:main

To deploy to staging:

# Copy prod db to the staging db:
heroku pg:copy replicache-license::DATABASE_URL DATABASE_URL -a replicache-license-staging --verbose

# TODO: should probably be pushing from a release branch

# Push the code, assuming you want to push from main. This should
# happen *after* copying the prod db because it will run migrations.
git push staging main

# Create a license on staging (using the licensing package get-license)
rm $(which get-license-cmd)
npm run build && npm link
npx get-license-cmd -s

To deploy to production:

heroku maintenance:on -a replicache-license
git push heroku main
# <verify it's all good>
heroku maintenance:off -a replicache-license

Rolling back

It's often more convenient to just roll forward, but here are the useful commands:

heroku releases -a <replicache-license|replicache-license-staging>
heroku releases:info vXX -a <replicache-license|replicache-license-staging>
heroku rollback vXX -a <replicache-license|replicache-license-staging>
