- 19. TypeScript isn’t a linter, but ESLint and Prettier do support TypeScript
- 20. “Cannot read property x of undefined” hurts in JavaScript > TypeScript’s optional chaining and strict null checks makes this easy

- Team Escal. Channels Alerts Staffed Priority SLA’s (screenshot of SLA escal.)
- For every feature, pinned items, purpose
- We make interactive runbooks which learn.
- Save questions for after the talk, due to the “lightning” nature of it.
- Not going to cover: Building a slack app Oauth UX intricacies
- What is devops? It’s tools designed to enable development and operations of your applications. CI/CD pipelines, alerting, monitoring, incident management.
- What makes sense to “tie in” to slack? Frequency of use Accessible (make a command available for someone who might not be able to run it on their own) Intricate Human decision making needed SOP vs incident
- “People are already there”. Everybody is in chat (as opposed to jenkins or other tools)
- Across the org
- Helpful for future you
- Can be included in
- All about making you more efficient and effective.
- So how can devops tools and chat work together
- Easiest: just have adhoc meetings in slack.
- Easier: bring all your relevant events (releases, incidents, service provider statuses) and discussions about those into slack. Aka the “firehose” pattern.
- Don’t push too much to slack (nginx logfiles in their entiriety) because of the 1 post/second limit.
- You can also build specific commands that integrate with devops tooling.
- Trigger a jenkins build. Show me the last 10 deployments for service X. Add this ip to my firewall and drop all the packets.
- You need to think about inputs. These include plain text, structured data from slack’s form controls (dates, select list) and emojis.
- Then ad your business logic (authorization, any specific business rules).
- Finally, connect to your other systems via webhook, API or SDK calls.
- Example of a slack app I built which lists my ec2 instances.
- Demo of list of ec2-instances and restart of ec2-instances in my test slack.
- Read this
- Or google for it.
- How can you discover slack commands? Docs, welcome messages, bots that exist in your workspace.
- Make sure to avoid escalation of privileges.
- Think about when you should drop out of slack. Sometimes you should just go to the tool. How do you capture the actions someone did “out of band”. Firehose will save you.
