bugsnag-roku

Bugsnag library for Roku

bugsnag-roku implements a Bugsnag error reporting client for Roku as a Task SceneGraph component which exposes an API hopefully familiar to user using Bugsnag in other programming languages.

There is currently no way to automatically handle all errors or collect user interaction data as breadcrumbs, so these actions are left to the library user to implement as they see fit.

Getting started

Create a Bugsnag account
Crate a new project in Bugsnag. The type shouldn't matter much but TV makes the most sense.
Install bugsnag-roku in your project with ropm install bugsnag-roku
Instantiate the Bugsnag client as soon as possible, set the config fields on it and start the task:

	m.top.bugsnagTask = CreateObject("roSGNode", "bugsnagroku_BugsnagTask")
	m.top.bugsnagTask.setFields({
		"releaseStage": "prod",
		"appVersion": appVersion,
		"apiKey": BUGSNAG_API_KEY
	})
	m.top.bugsnagTask.control = "RUN"

Use the fields and functions exposed on the BugsnagTask component to report events to Bugsnag.

bugsnagroku_ is automatically added to all component and function names by ropm. At the moment, copying files into your project manually isn't supported out of the box because of ropm's partial prefixing. You would have to open all the source code files and remove all bugsnagroku_ prefixes.

Configuration fields

Field	Default value	Description
releaseStage	""	Release stage like production, prod, dev, development, stage, QA, test, etc. Can be any string.
appVersion	""	Version of the application that's using bugsnag-roku. If the version in the manifest is correct, this can be retreived from an instance of `roAppInfo`
apiKey	""	Your Bugsnag API key. Each project has a different API key.
user	{}	Initial user data. This can be updated later using `bugsnagroku_updateUser()` function. If user ID is not set, the library may set it to device IP automatically (see below)
reportChannelClientId	true	Whether to report channel client ID as part of device info. Client channel ID is unique per device/channel combination. It can uniquely identify a user within a Roku channel but not between multiple channels.
useIpAsUserId	true	Whether to set user ID to device IP if it's not set in the initial user data.
logNetworkErrors	false	Whether to log any network errors that may be returned when making requests to Bugsnag API.

API reference

All fields and functions are exposed on the instance of bugsnagroku_BugsnagTask component.

<field id="notify" type="AssocArray" onChange="bugsnagroku_notify" />

Report an event to Bugsnag, by setting the error data as associative array to the notify field.

m.top.bugsnagTask.notify = { errorClass: errorClass, errorMessage: errorMessage, severity: severity, context: context, exceptions: exceptions, metadata: metadata }

Param	Description
errorClass	Error class shown in Bugsnag UI. Since there is no automatic error handling in BrightScript, this can be any string. Something like "HttpError" or "ValidationError" is recommended since Bugsnag UI is designed to show error classes like that from other languages.
errorMessage	Error message shown in Bugsnag UI. This should concisely describe what happened so that it can be easily both read and searched.
severity	Event severity as defined by Bugsnag API. It can be `error`, `warning` or `info`. If an invalid value is supplied, the library will default to `error`.
context	Location where the error happened. In web UIs this is the URL. Since Roku has no notion of a URL, this can be omitted, but it might be a good idea to send at least the name of the file where error occurred.
metaData	Metadata to attached to event.
exceptions	Array of errorClass exceptions related to the error happened

bugsnagroku_updateUser(userDiff as Object)

Update user object sent with each event. The userDiff parameter is an associative array mapping keys to update to their new values. In simple terms, any existing user associative array will be merged with the provided parameter.

bugsnagroku_leaveBreadcrumb(name as String, breadcrumbType as String, metaData={})

Add a new breadcrumb. All breadcrumbs are sent with every reported event.

Param	Description
name	Breadcrumb name shown in Bugsnag UI
breadcrumbType	Breadcrumb type as defined by Bugsnag API. May be `navigation`, `request`, `process`, `log`, `user`, `state`, `error`, `manual`. Unlike most other Bugsnag libraries, bugsnag-roku is unable to automatically detect any of those types of events.
metaData	Metadata attached to the breadcrumb

Contributing

Contributions are welcome. Before making a contribution, might be a good idea to make sure you're on the same wavelength as maintainers by opening an issue and discussing whatever you want to fix, refactor or add to the library.

Code Style

Flow control structures such as if..else..end if, for..end for and keywords such as print, function, invalid, etc should be all lowercase.
All function, no sub
System functions and variables should be PascalCase, for example CreateObject(), ToStr(), GetScene(), etc. Exceptions are m and m.top
Library functions and variables should be camelCase, like leaveBreadcrumb() and updateUser()
Use REM for important comments for visibility
No then after if condition
All HTTP requests are done on the task thread
