With the introduction of code branching into the OutSystems platform, development teams have the flexibility to collaborate more effectively. From feature branches, to refactoring, to hotfixing production code, OutSystems’ new branching capability allows you to maintain power of built-in dependency analysis along with flexibility that multiple parallel code lines enables.

- 3. | Branching your way to low-code perfection Problem Branching ● As application teams grow, delivery slows down because multiple developers compete to change the same code ● Developers need to deliver at different paces and release teams need to control what is delivered
- 4. | Branching your way to low-code perfection Goal Branching ● Enable collaborative development on OutSystems ● Deliver a new branching capability to allow developers to work concurrently on the same code ● Provide an isolated runtime for continuous integration to deliver at a faster pace

- 49. | Branching your way to low-code perfection Differences to High Code ● One isolated runtime is granted for each developer. ● Not possible to create new runtimes. ● LifeTime only stages code that is in trunk, meaning, not possible to stage code that is isolated runtimes. ● Isolated runtimes share the database with the environment; there is no isolation of data. ● Each isolated runtime consumes extra memory on Development Environment.
- 50. | Branching your way to low-code perfection ● Support Reactive Web and Mobile runtime ● Improved Merge experience ● “Pull-request”

Editor's Notes
- [2 min] Introduce yourself
- Developer isolation use case
- Demo bugfix use case
- In application list, there’s the SHARED AREA
- When opening a module, it is focused on PUBLIC AREA
- Developer does the fix
- Developer may validate the fix in his “Developer Area”
- The URL of the branch version is different (adds username after application name; her OrderManagement/anb/Dashboard.aspx)
- Since it’s fixed, the developer publishes to PUBLIC AREA, which issues a warning that it’s going to MERGE with TRUNK
- Developer isolation use case
- The Tech Lead, opens Service Studio and connects to junior developer’s area
- The Tech Lead opens module from junior developer’s area
- And so, if doing 1CP, module will be updated in junior developer’s area
- Multiple teams at different paces use case
- Demo new feature use case
- The developer may open a module and do significant changes
- Developer is adding a screen
- The developer will validate changes BEFORE sharing with everybody else
- After publishing in SHARED AREA, developer may actually run it
- The URL is different from the Public Area because it includes the developers username
- The new functionality is accessible from outside, meaning it may be validated before merged into trunk
- Cherry-pick release use case
- Demo code review use case
- Release Manager validates functionality; then he opens Service Studio
- The Release Manger connects to junior developer’s area
- The Release Manager opens module from junior developer’s area
- The Release Manager may validate changes, by doing a “Compare and Merge” the module opened from developer’s area and the Public Area
- The Release Manager may check the code
- The Release Manager may then MERGE changes into TRUNK
- The feature becomes available in the trunk
- Fix production code use case
- Demo hotfix use case
- The senior developer connects to pre-prod environment
- There is no feature branching here!
- After fixing the code, the senior developer publishes to Pre-Prod environment
- LifeTime signals a hotfix in Pre-Prod environment
- The senior developer deploys to production
- The senior developer merges changes in development environment
- In the end, all environments are synched
- During next year...
