Redwood v2.0.0 is now available!

Don’t panic

Two point oh?! What is happening?! Reading Tom’s latest blog post should ease some of your worries: Major Version Numbers are Not Sacred. Along with v1, this major version will be a part of the same Redwood epochal version, Arapaho Forest.

There are only a few breaking changes in this release, and if you don’t use some of these features then this’ll be practically the same as a normal ol’ minor-version update for you!

Having said that, here are the three breaking changes:

Breaking Changes

Linting import order

:information_source: This is a small change but affects all users.

Previously, Redwood didn’t validate the order of imports. Import something from a local file before an npm package? Space between import groups? Nothing to see here:

But since we use this rule in the framework itself, and since Redwood’s opinionated, we consider its exclusion from projects a miss. So as of v2.0.0, Redwood lints the order of imports and reports them as an error. So if you’re seeing red squiggles on import declarations after upgrading, this’s why:

image

Although they’re annoying and make you feel like you did something wrong, in of themselves, these squiggles are harmless. The real consequences come if you’re running lint in CI because now that step will fail. But luckily it’s a super easy fix.

How to upgrade

TL;DR, after upgrading, run yarn rw lint --fix.

Although it really is that simple, we recommend going the extra mile to keep your git history clean by stashing whatever changes you have, running the command, then committing the changes:

# after stashing, or at least when your working directory is clean
yarn rw lint --fix
git add .
git commit -m "style: order imports"

Note that running yarn rw lint --fix may alert you to other errors, like unused variables, that the lint command can’t fix automatically. That’s ok—it should’ve fixed the order of imports still since it’s just a matter of rearranging import declarations.

Congratulations, you’re on v2.0.0! But if you’re deploying via baremetal or using auth in serverless functions, keep reading.

Baremetal deploy

:information_source: If you don’t use the baremetal deploy strategy, this doesn’t affect you. You can safely skip this section. Otherwise, expand the “Details” section and follow along.

This release features some major updates to the Baremetal deploy option! Let’s break them down along with any changes you’ll need to make to your server and deploy.toml file.

New Code Update Strategy

We’ve got a good news/bad news situation. The good news: you can now deploy a branch other than main and code updates are much more reliable using git clone! The bad news is that you’re going to have to do some more config and server setup to get this latest version working. But once you do, everything will be awesome!

PM2

Baremetal now requires that PM2 be installed globally, rather than a development dependency of your app. This has to do with the new directory structure we’re going to create and where pm2 is executed from (short version: it’s run outside of your actual codebase, so yarn pm2 won’t be available).

You’ll want to remove your existing pm2 services. This will cause downtime, so be mindful if running in a production environment. Run the following commands on the server:

yarn pm2 delete all

Now install PM2 globally: PM2 - Installation | Guide | PM2 Documentation

PM2 will still be running in memory as the previous yarn pm2 version, so you can run this command to update the process:

pm2 update

If you previously setup PM2 to run at startup, you’ll need to update to the new global install instead:

yarn pm2 unstartup
pm2 startup

Be sure to remove pm2 in your app’s package.json file.

Directory Structure

Next we’ll need to update the directory structure inside your deploy path.

Current directory structure:

└── var
    └── www
        └── myapp
            ├── api
            ├── web
            ├── ...

New directory structure:

└── var
    └── www
        └── myapp
            ├── .env <────────────┐
            ├── current ────────┐ │
            └── 20220420120000 <┘ │
                ├── .env ─────────┘
                ├── api
                ├── web
                ├── ...

The current symlink is updated at the end of a deploy to point to the latest release (assuming a successful clone and build). This means all build packages in web/dist and api/dist remain self-contained in their parent timestamp directory. This makes a rollback trivial: just point the current symlink to the previous directory and restart your web/api processes! yarn rw deploy baremetal --rollback is coming soon! A shared .env file exists in the root of your app path and each copy of the codebase will contain a symlink back out to this file.

The easiest way to update to this structure is to simply remove everything inside of your currently deploy directory (like /var/www/myapp) and let yarn rw deploy baremetal --first-run set everything up for you. You’ll want to keep your .env file, however:

cd /var/www/myapp
mv .env ..
rm -rf *
mv ../.env .

Config Updates

You’ll need to add a new option to your ecosystem.config.js file for any processes that run within the context of your app:

module.exports = {
  apps: [
    {
      name: 'serve',
+     cwd: 'current',
      script: 'node_modules/.bin/rw',
      args: 'serve',
      instances: 'max',
      exec_mode: 'cluster',
      wait_ready: true,
      listen_timeout: 10000,
    }
}

You’ll also need to add the repo config setting and optionally branch to your deploy.toml file (also note the new environment name prefixing servers, more on that in a moment):

[[production.servers]]
host = "myserver.com"
username = "user"
agentForward = true
sides = ["api", "web"]
path = "/var/www/myapp"
processNames = ["api"]
+ repo = "git@github.com:myorg/myrepo.git"
+ branch = "main"

The branch will default to main if not set.

Make sure everything is saved, committed, and pushed up to your repo because we’re ready for the first deploy.

First Deploy

Run the deploy command for the first time to setup the directory structure, check out your code, and build and start monitoring your processes:

yarn rw deploy baremetal --first-run

And that’s it! If everything started up correctly then you’re good to go for future deploys. If not check out https://redwoodjs.com/docs/deployment/baremetal#troubleshooting

If you want to perform a one-time deploy of a branch other than the one listed in deploy.toml you can do so via a flag at deploy time:

yarn rw deploy baremetal --branch=staging

Multiple Environment Support

Baremetal deploy now supports deploying to multiple environments! If you’ve got production, and staging, and whatever else, this update is for you. If you’re setting up a new deploy from scratch with yarn rw setup deploy baremetal you’re good to go. If you have an existing deploy.toml file you may want to make an update:

Instead of just [[servers]] prefixing your server config, make it [[environment.servers]] where environment is the actual name of your environment. For example:

[[production.servers]]
host: 'server.com'
# remaining config...

[[staging.servers]]
host: 'staging.server.com'
# remaining config...

You can still have multiple servers in an environment, just repeat the [[servers.production]] heading multiple times, one for each block of server config:

[[production.servers]]
host: 'prod1.server.com'
# remaining config...

[[production.servers]]
host: 'prod2.server.com'
# remaining config...

This new syntax is optional: keeping your default [[servers]] name will act as production (and leaving off the stage name in yarn rw deploy baremetal will default to use these server settings).

Maintenance Page

You can now enable/disable a maintenance page with the Baremetal deploy! Simply create web/src/maintenance.html containing your maintenance message. (For now this page must just be plain HTML, but if the need is there it should be possible to add the page to the webpack/babel pipeline and make it a full React app. If this is something you’d like to work on, get in touch!)

When you’re ready to enable your maintenance page on the site:

yarn rw deploy baremetal --maintenance up

And to take it back down:

yarn rw deploy baremetal --maintenance down

This command respects the environment argument so you can put it up on just your staging environment, for example:

yarn rw deploy baremetal staging --maintenance up

That’s it! This feature works by turning web/dist/index.html into a symlink pointing to web/src/maintenance.html. As long as your server is configured to check for the existence of 200.html for the web side and serve that for any URL request that isn’t the API, users should see the maintenance page the time time your site loads. Note that if a user already has your site loaded, they will most likely be able to keep clicking through your pages since everything is already cached in the browser. We’re thinking about adding a “ping” feature that, on each page request, would check with the server to see if the maintenance page should be displayed, and if so interrupt their browsing session to show it. If this is something you’d like to work on, let us know by opening an issue or PR!

Old Deploy Cleanup

Baremetal will now cleanup old deploy codebase directories at the end of a deployment! It defaults to keep the last 5 deployments, but this can be configured in deploy.toml with the keepReleases option:

[[servers.production]]
host = "server.com"
username = "ubuntu"
agentForward = true
sides = ["api", "web"]
path = "/var/www/myapp"
processNames = ["api"]
repo = "git@github.com:myorg/myrepo.git"
branch = "main"
+ keepReleases = 5

Why keep around old deploys? In case something goes horribly wrong and you need to rollback!

This config setting is optional and will default to keeping the last 5 deploys if not set.

Rollback

If you deploy and find something has gone horribly wrong, you can now rollback your deploy to the previous release!

yarn rw deploy baremetal --rollback

You can even rollback multiple deploys, up to the total number you still have denoted with the keepReleases option:

yarn rw deploy baremetal --rollback 3

Note that this will not rollback your database—if you had a release that changed the database, that updated database will still be in effect, but with the previous version of the web and api sides. Trying to undo database migrations is a very difficult proposition and isn’t even possible in many cases.

Make sure to thoroughly test releases that change the database before doing it for real!

There’s no Rollforward: you probably rolled back because the newer deploy is faulty! Performing a new deploy would be the equivalent action to rolling the codebase forward to a newer release.

Override Default yarn and pm2 commands

You can now override the default yarn and pm2 exec commands with your own custom command. Why would you want to do this? Tools like doppler provide their own CLI command to inject secrets into your shell, and you then chain on the command you would normally run, like so:

doppler run -- yarn rw prisma migrate deploy

To set this, add the following to your deploy.toml file:

[[servers.production]]
host = "server.com"
username = "user"
agentForward = true
sides = ["api","web"]
path = "/var/www/app"
processNames = ["serve"]
repo = "git@github.com:myorg/myapp.git"
branch = "main"
keepReleases = 5
+ packageManagerCommand = "doppler run -- yarn"
+ monitorCommand = "doppler run -- pm2"

These two settings are optional and will default to the existing yarn and pm2 commands if not set.

Lifecycle Events

When in the course of a deploy, if it becomes necessary to run additional commands not provided for in the stock list of Baremetal steps, you can turn to lifecycle events. These events allow you to run custom commands before or after the existing commands. Here are the current steps in a deploy:

  1. update - the latest code is cloned from the server
  2. symlinkEnv - a symlink is created in the newly cloned codebase pointing to the .env file in the main app directory
  3. install - latest dependencies are installed
  4. migrate - database and db migrations are run
  5. build - the api and/or web sides are built
  6. symlinkCurrent - a symlink is created from the main app directory to the latest deploy directory
  7. restart - PM2 restarts any services listed
  8. cleanup - old deploy directories are removed

There are three ways you can define your lifecycle events: globally (runs for all environments and all servers), environment-specific (runs for all servers in a given environment) or server-specific (runs only for a single server).

Global Lifecycle Events

Add a top level [before] or [after] key to your deploy.toml, listing which step you want to hook into and what command to run:

[before]
install = 'touch install.lock'

[after]
install = 'rm install.lock'

[[production.servers]]
host = 'server.com'
# ...

You can hook into multiple steps, and execute multiple custom commands:

[before]
install = ['touch install.lock', 'rm logs/deploy.log']
cleanup = 'echo "Removing old deploys" > "deploy.log"'

[[production.servers]]
host = 'server.com'
# ...

Environment Lifecycle Events

[production.before]
install = 'touch install.lock'

[staging.after]
build = 'touch debug-enable'

[[production.servers]]
host = 'server.com'
# ...

[[staging.servers]]
host = 'stage.server.com'
# ...

Server Lifecycle Events

[[production.servers]]
host = 'server.com'
before.install = 'touch install.lock'
# ...

Important Considerations

All commands are run inside the newly deployed code directory (like /var/www/myapp/20220520120000) except update and cleanup! These are run in the path defined in deploy.toml since they are independent of any single release.

The build and restart steps may run multiple times based on how many sides you’re building or services you’re restarting. Any defined before/after lifecycle events will run as many times as the original step is run, so plan accordingly: make your command idempotent so that it can be run multiple times without side effects.

Auth in serverless functions

:information_source: If you don’t use useRequireAuth in serverless functions, this doesn’t affect you. You can safely skip this section. Otherwise, expand the “Details” section below and follow along.

Previously, the behavior of useRequireAuth in serverless functions differed depending on whether auth-related headers were set. In this release, we rectified it so that it behaves the same whether or not headers are set.

When calling a serverless function wrapped in useRequireAuth with no auth-related headers set, Redwood continues invoking the serverless function. But if the auth-provider header is set and the token is invalid, the function throws and returns a 401 error. This is inconsistent behavior for otherwise similar scenarios. In v2.0.0, we’ve changed it so that in both scenarios it continues executing.

Note that this breaking change is just behavioral. It’s up to you as the developer to make sure you call requireAuth or use the isAuthenticated variable inside the serverless function to enforce authentication. That is, useRequireAuth just makes the authentication context available, but doesn’t enforce authentication in of itself.

:information_source: Note that if you think the name useRequireAuth is confusing, we do too and plan on renaming it. We couldn’t settle on a better alternative in time for this release, otherwise we would’ve included it.

2.0 is super huge! (and I’m glad you’re using major version numbers for breaking changes)

would you consider including an explanation of what ‘baremetal’ means, where it’s used, and why it’s used? (or links to explanations)

for instance, I would like to deploy to EKS – is that baremetal?

thanks!

Al;

Check out the docs: Introduction to Baremetal | RedwoodJS Docs

Baremetal just means the raw server, no other intermediary like Netlify or someone doing the deploy and serving the files for you: you run a web server (either yarn rw serve or a standalone web server like nginx) and internet traffic goes directly to that server! Even more scalable with a load balancer out front, but the Baremetal deploy doesn’t know anything about those. Yet. :smiling_imp:

It’s in the works and @danny is the project lead.

If you have the time available, it would be very helpful to know what your specific needs/use case would be — could you post in a new forum topic and loop in Danny?

Also, you might be interested in this incoming PR to add prerendering to Redwood Cells (aka dynamic SSG for pages with Cells):
