Project Architecture

Compiler Status

You can see on the status bar of the IDE that your compiler is currently having errors or is compiled successfully:

.theia/compiler_status.json is a file that is used to store the status of the TS Compiler (Watcher). When the status is true, that means you have no Compiler error on the project and you can safely apply changes in order to see the changes on the Mobile Device.

info

We recommend keeping the .theia/compiler_status.json file in .gitignore since it is totally used for local purposes.
