Probably the best Gerber viewer on the internet. @tracespace/view uses the pcb-stackup library to render Gerber and NC drill files as SVGs in your browser, without ever sending your files to a server.
Your renders are saved locally, so you can check out your boards without constantly having to re-upload your Gerber files.
The app is very similar to a typical React + Redux application. A central state store is available all through-out the app, and much of the UI is derived directly from that state.
The state can be changed by dispatching a specific action to the store, which will fold the action into the state. As the action is being processed, it will pass through a series of middleware that can trigger side-effects, like triggering a render.
For more information, see the state module
The app runs pcb-stackup and various file reading libraries in a separate thread from the main UI via a Web Worker. The render worker responds to and emits application store actions via the [render middleware][render-middleware]/
For more information, see the render module.
Source files and their associated renders, as well as application preferences, are stored locally using IndexedDB. The app has two databases:
BoardDatabase- Accessed exclusively by the render worker
- Stores board information, layer information, and source files
AppDatabase- Accessed from the main UI thread via the settings middleware
- Stores application preferences and information
The tracespace view application collects anonymous usage data if you opt-in to tracking. See the analytics module for more information
To debug the application state, you can change the app's log level using your browser's JavaScript console:
localStorage.setItem('logLevel', 'debug')Available log levels are:
debug(default in development)infowarn(default in production)error
At logLevel: 'debug', all actions and state changes will be logged
