App version resolver events

app-version-progress

Generated when RVM tries each manifest in the list of fallbackManifests, validate it and see if it's compatible with the system app.

//This response has the following shape:
{
type: 'app-version-progress',
manifest: 'https://cdn.openfin.co/release/system-apps/notifications/1.13.0/app.json', // A manifest in the fallbackManifest list
srcManifest: 'https://cdn.openfin.co/myapp.json' // To keep track of the original manifest url
}

runtime-status

Generated when RVM checks runtime availability.

//This response has the following shape:
{
type: 'runtime-status',
version: '29.105.71.32', // runtime version
exists: false, // check if the runtime already exists on the machine
writeAccess: true, // check if the runtime directory has write access
reachable: true, // check if the runtime asset location is reachable/downloadable
healthCheck: true, // check if there is runtime health check
error: 'Not able to resolve runtime version' // give an error message if runtime version cannot be resolved
}

app-version-complete

Generated when RVM has successfully found the target runtime version and (about to) delegate launch to the runtime.

//This response has the following shape:
{
type: 'app-version-complete',
manifest: 'https://cdn.openfin.co/release/system-apps/notifications/1.13.0/app.json', // A manifest in the fallbackManifest list
srcManifest: 'https://cdn.openfin.co/myapp.json' // To keep track of the original manifest url
}

app-version-error

Generated when RVM failed to find an available runtime version after trying each manifest in the list of fallbackManifests.

//This response has the following shape:
{
type: 'app-version-error',
srcManifest: 'https://cdn.openfin.co/myapp.json', // To keep track of the original manifest url
error: 'All fallback manifest URLs failed' // error message
}
