LIQUID FIRE?
🎉 TESTS PASSING!
GOALS FOR THE TALK▸ next LTS (2.8.x) √
▸ tests passing √
▸ no deprecations
TO UPGRADE OR NOT TO UPGRADE?
🎉 LESS DEPRECATIONS!
ember-cli 2.8.0 ! 2.10.0
ember-cli-app-version ^1.0.0 ! ^2.0.1
ember-cli-jshint ^1.0.0 ! ^2.0.1
ember-cli-qunit ^2.1.0 ! ^3.1.0
ember-cli-release ^0.2.9 ! ^1.0.0-beta.2
ember-load-initializers ^0.5.1 ! ^0.6.3
EVERYTHING LEFT IS EMBER CORE
GOALS FOR THE TALK▸ next LTS (2.8.x) √
▸ tests passing √
▸ no deprecations √
STEP 4: DEPLOY + MONITOR
“SAFE” DEPLOY / TESTING▸ ember-cli-deploy-redis *
▸ use index keys to help
▸ keep an eye out for errors
▸ test critical flows
* SEE MY TALK ON EMBER-CLI-DEPLOY STRATEGIES FOR MORE INFO
MONITOR JS ERRORS▸ new relic
▸ sentry
▸ track.js
▸ etc, etc
ONGOING MAINTENANCE
PAY ATTENTION TO DEPRECATIONS
▸ don’t have to fix all deprecations when upgrading minor versions
▸ use deprecation workflow file as a log
USE THROW HANDLER
window.deprecationWorkflow = window.deprecationWorkflow || {}; window.deprecationWorkflow.config = { workflow: [ { handler: "silence", matchId: "ember-getowner-polyfill.import" } ] };
USE THROW HANDLER
window.deprecationWorkflow = window.deprecationWorkflow || {}; window.deprecationWorkflow.config = { workflow: [ { handler: "silence", matchId: “ember-htmlbars.ember-handlebars-safestring“ } ] };
USE THROW HANDLER
window.deprecationWorkflow = window.deprecationWorkflow || {}; window.deprecationWorkflow.config = { workflow: [ { handler: "throw", matchId: “ember-htmlbars.ember-handlebars-safestring“ } ] };
