@ -28,6 +28,19 @@ To bundle up the final UI into Geth, run `go generate`:
$ go generate ./dashboard
```
Since JavaScript doesn't provide type safety, [Flow][Flow] is used to introduce and check types. These types are only useful during the development, so at the end of the day Babel will strip them.
To take advantage of types the IDE needs to be prepared for them.
In case of [Atom][Atom] a configuration guide can be found [here][Atom config].
Install the [Nuclide][Nuclide] package for Flow support, make sure it installs all of its support packages by enabling `Install Recommended Packages on Startup`, and set the path of the `flow-bin` which were installed previously by `npm`.
For more IDE support install the `linter-eslint` package too, which finds the `.eslintrc` file, and provides real-time linting.
Atom warns, that these two packages are incompatible, but they seem to work well together.
For third-party library errors and their auto-complete [flow-typed][flow-typed] is used.
To visualize the hidden elements (e.g. `node_modules`), uncheck the `Exclude VCS Ignored Path` in `Settings > Core`.
To visualize the white spaces, check `Show invisibles` in `Settings > Editor`.
To use Sublime-like minimap, install the `minimap` package.
In case of trouble related to the Atom UI, run `atom --clear-window-state`.
### Have fun
[Webpack][Webpack] offers handy tools for visualizing the bundle's dependency tree and space usage.
