What doe scale mean in this context? Hundreds of developers at Airbnb now use Typescript as their primary language for front-end development.
The idea was raised at the front-end working group meeting where they talk about new technologies, make and discuss proposals.
These are deliberate decisions about what they commit to as a team.
They used pilot teams first who were then sent a survey to see if they should keep using it.
There are types maintained in a public package for packages which aren’t typed with Typescript. Sharing is caring.
Codemods can help you do large refactors.
Impact of introducing Typescript:
- Fewer bugs - externally it had been reported to reduce number of bugs by 15%. After analysis of recent bugs Brie found that 38% of those bugs would have been preventable with Typescript.
- A better developer experience.
- End to end type safety as types can be used across front and back-end.
