Moving to TS
Why
-
Fewer Bugs
-
Better DX
-
Edge improvements
Fever bugs
Possible bug
Fix, after it brakes on test or prod
API removal/rename
There is no foo method anymore.
And we could have like 30+ places like this in a project
Things like a simple typo
Better
Developer Experience
JSX api help
JSX api help (custom component)
// Before
if (foo && foo.bar && foo.bar.baz) {
// ...
}
// After-ish
if (foo?.bar?.baz) {
// ...
}Optional Chaining
VSCode
IntelliSense works using TypeScript, even in projects without TypeScript
IntelliSense - code completion, parameter info, quick info, and member lists
Edge engine improvements
Edge engine docgen version
- data missing (reducers)
- server widgets
- it's dangerous to refactor widget scheme
- scheme shape duplication
- using server props, without declaring them
- hard to maintain big projects
- the build is slow, as we use Docgen library
- scene generation is too complicated to improve (abstract syntax trees)
- no access to components.json before the main src build, no way to get default values for widgets
TS version
- data filled with a default value
- server widgets
- easy to refactor widget schema
- no scheme shape duplication
- no way, of using server props, without declaring them
- easy to maintain
- Webpack build doesn't need to parse stats
- scene generation is simple
- access to components.json before the main src build
Using widget string
Using widget repeater
Using auto generated interface
Using several widgets together
Updatgin schema
Go to vs code
