An object representing the core of OpenFin Runtime. Allows the developer to perform system-level actions, such as accessing logs, viewing processes, clearing the cache and exiting the runtime as well as listen to system events.

Hierarchy

Accessors

  • get me(): Identity
  • Provides access to the OpenFin representation of the current code context (usually a document such as a View or Window), as well as to the current Interop context.

    Useful for debugging in the devtools console, where this will intelligently type itself based on the context in which the devtools panel was opened.

    Returns Identity

Methods

  • Adds a listener to the end of the listeners array for the specified event.

    try {
    const certificationInfo = await fin.System.isAppCertified(manifestUrl);
    } catch(err) {
    console.error(err)
    }
  • Runs an executable or batch file. A path to the file must be included in options.
    A uuid may be optionally provided. If not provided, OpenFin will create a uuid for the new process.
    Note: This method is restricted by default and must be enabled via API security settings. Also, this api has an enhanced permission set to make it less dangerous. So application owners can only allow to launch the assets owned by the application, the enabled downloaded files or the restricted executables.

    Parameters

    Returns Promise<Identity>

    Remarks

    If an unused UUID is provided in options, it will be used. If no UUID is provided, OpenFin will assign one. This api has an enhanced permission set to make it less dangerous. So application owners can only allow to launch the assets owned by the application, the enabled downloaded files or the restricted executables.

    Note: Since appAssets relies on the RVM, which is missing on MAC_OS, 'alias' is not available. Instead provide the full path e.g. /Applications/Calculator.app/Contents/MacOS/Calculator.

    Example

    Basic Example:

    fin.System.launchExternalProcess({
    path: 'notepad',
    arguments: '',
    listener: function (result) {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    Promise resolution:

    //This response has the following shape:
    {
    uuid: "FB3E6E36-0976-4C2B-9A09-FB2E54D2F1BB" // The mapped UUID which identifies the launched process
    }

    Listener callback:

    //This response has the following shape:
    {
    topic: "exited", // Or "released" on a call to releaseExternalProcess
    uuid: "FB3E6E36-0976-4C2B-9A09-FB2E54D2F1BB", // The mapped UUID which identifies the launched process
    exitCode: 0 // Process exit code
    }

    By specifying a lifetime, an external process can live as long the window/application that launched it or persist after the application exits. The default value is null, which is equivalent to 'persist', meaning the process lives on after the application exits:

    fin.System.launchExternalProcess({
    path: 'notepad',
    arguments: '',
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    },
    lifetime: 'window'
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    Note: A process that exits when the window/application exits cannot be released via fin.desktop.System.releaseExternalProcess.

    By specifying a cwd, it will set current working directory when launching an external process:

    fin.System.launchExternalProcess({
    path: 'cmd.exe',
    cwd: 'c:\\temp',
    arguments: '',
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    Example using an alias from app.json appAssets property:

    "appAssets": [
    {
    "src": "exe.zip",
    "alias": "myApp",
    "version": "4.12.8",
    "target": "myApp.exe",
    "args": "a b c d"
    },
    ]
    //  When called, if no arguments are passed then the arguments (if any)
    // are taken from the 'app.json' file, from the 'args' parameter
    // of the 'appAssets' Object with the relevant 'alias'.
    fin.System.launchExternalProcess({
    //Additionally note that the executable found in the zip file specified in appAssets
    //will default to the one mentioned by appAssets.target
    //If the the path below refers to a specific path it will override this default
    alias: 'myApp',
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    Example using an alias but overriding the arguments:

    "appAssets": [
    {
    "src": "exe.zip",
    "alias": "myApp",
    "version": "4.12.8",
    "target": "myApp.exe",
    "args": "a b c d"
    },
    ]
    //  If 'arguments' is passed as a parameter it takes precedence
    // over any 'args' set in the 'app.json'.
    fin.System.launchExternalProcess({
    alias: 'myApp',
    arguments: 'e f g',
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    It is now possible to optionally perform any combination of the following certificate checks against an absolute target via fin.desktop.System.launchExternalProcess():

    "certificate": {
    "serial": "3c a5 ...", // A hex string with or without spaces
    "subject": "O=OpenFin INC., L=New York, ...", // An internally tokenized and comma delimited string allowing partial or full checks of the subject fields
    "publickey": "3c a5 ...", // A hex string with or without spaces
    "thumbprint": "3c a5 ...", // A hex string with or without spaces
    "trusted": true // A boolean indicating that the certificate is trusted and not revoked
    }

    Providing this information as part of the default configurations for assets in an application's manifest will be added in a future RVM update:

    fin.System.launchExternalProcess({
    path: 'C:\\Users\\ExampleUser\\AppData\\Local\\OpenFin\\OpenFinRVM.exe',
    arguments: '--version',
    certificate: {
    trusted: true,
    subject: 'O=OpenFin INC., L=New York, S=NY, C=US',
    thumbprint: '‎3c a5 28 19 83 05 fe 69 88 e6 8f 4b 3a af c5 c5 1b 07 80 5b'
    },
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });

    It is possible to launch files that have been downloaded by the user by listening to the window file-download-completed event and using the fileUuid provided by the event:

    const win = fin.Window.getCurrentSync();
    win.addListener('file-download-completed', (evt) => {
    if (evt.state === 'completed') {
    fin.System.launchExternalProcess({
    fileUuid: evt.fileUuid,
    arguments: '',
    listener: (result) => {
    console.log('the exit code', result.exitCode);
    }
    }).then(processIdentity => {
    console.log(processIdentity);
    }).catch(error => {
    console.log(error);
    });
    }
    });

    Launching assets specified in the app manifest:

    Sample appAssets section in app.json

        "appAssets": [
    {
    "src": "http://filesamples.com/exe.zip",
    "alias": "myApp",
    "version": "4.12.8",
    "target": "myApp.exe",
    "args": "a b c d"
    },
    {
    "src": "http://examples.com/exe.zip",
    "alias": "myApp2",
    "version": "5.12.8",
    "target": "myApp2.exe",
    "args": "a b c"
    }
    ]

    This permission allows for launching of all assets specified in the above appAssets section. ("myApp" and "myApp2"):

        "permissions": {
    "System": {
    "launchExternalProcess": {
    "enabled": true,
    "assets": {
    "enabled": true
    }
    }

    }

    This permission allows for launching of only the "myApp" asset in the above appAssets section, as defined in srcRules:

        "permissions": {
    "System": {
    "launchExternalProcess": {
    "enabled": true,
    "assets": {
    "enabled": true
    "srcRules": [
    {
    "match": [
    "*://filesamples.com/*"
    ],
    "behavior": "allow"
    },
    {
    "match": [
    "<all_urls>"
    ],
    "behavior": "block"
    }
    ]
    }
    }
    }
    }

    Launching downloaded files:

        "permissions": {
    "System": {
    "launchExternalProcess": {
    "enabled": true,
    "downloads": {
    "enabled": true
    }
    }
    }
    }

    This permission allows to launch all the executables:

        "permissions": {
    "System": {
    "launchExternalProcess": {
    "enabled": true,
    "executables": {
    "enabled": true
    }
    }
    }
    }

    This permission only allows launching of executables whose file paths match the corresponding pathRules:

        "permissions": {
    "System": {
    "launchExternalProcess": {
    "enabled": true,
    "executables": {
    "enabled": true
    "pathRules": [
    {
    "match": [
    "/Windows/System32/*.exe"
    ],
    "behavior": "allow"
    },
    {
    "match": [

    ],
    "behavior": "block"
    }
    ]
    }
    }
    }
    }
  • Experimental

    Launch application using a manifest URL/path. It differs from Application.startFromManifest in that this API can accept a manifest using the fin protocol.

    Parameters

    • manifestUrl: string

      The manifest's URL or path.

    • opts: RvmLaunchOptions = {}

      Parameters that the RVM will use.

    Returns Promise<Manifest>

    Remarks

    Supports protocols http/s and fin/s, and also a local path.

    Note: This API is Windows only.

    Example

    This API can handle most manifest types. Some examples below.

    Traditional:

    const manifest = await fin.System.launchManifest(
    'https://demoappdirectory.openf.in/desktop/config/apps/OpenFin/HelloOpenFin/app.json');
    console.log(manifest);

    Platform:

    const manifest = await fin.System.launchManifest('https://openfin.github.io/platform-api-project-seed/public.json');
    console.log(manifest);

    Launching traditional manifest into a platform:

    const manifest = await fin.System.launchManifest(
    'https://openfin.github.io/platform-api-project-seed/public.json?\
    $$appManifestUrl=https://demoappdirectory.openf.in/desktop/config/\
    apps/OpenFin/HelloOpenFin/app.json');
    console.log(manifest);

    Launching with RVM options:

    const manifest = await fin.System.launchManifest('https://openfin.github.io/platform-api-project-seed/public.json',
    { noUi: true, userAppConfigArgs: { abc: '123', xyz: '789' } });
    console.log(manifest);

    Local Path:

    const manifest =  await fin.System.launchManifest('file://c:\\path\\to\\manifest\\file.json');
    console.log(manifest);

    Launching with RVM 'subscribe' option:

    This option allows users to subscribe to app version resolver events when calling launchManifest with fallbackManifests specified.

    fin.System.launchManifest('fins://system-apps/notifications/app.json', { subscribe: (launch) => {
    launch.on('app-version-progress', (progress) => {
    console.log("Trying manifest " + progress.manifest)
    });

    launch.on('runtime-status', (status) => {
    console.log("Runtime status: " + JSON.stringify(status));
    });

    // RVM has successfully found the target runtime version
    launch.on('app-version-complete', (complete) => {
    console.log("Parent app " + complete.srcManifest + " resolved to " + complete.manifest);
    launch.removeAllListeners();
    });

    // RVM failed to find an available runtime version
    launch.on('app-version-error', (error) => {
    console.log("Failed to resolve " + error.srcManifest + " from the fallbackManifests");
    launch.removeAllListeners();
    });
    }
    });
  • Parameters

    • type: string | symbol

    Returns number

  • Parameters

    • type: string | symbol

    Returns Function[]

  • Writes the passed message into both the log file and the console.

    Parameters

    • level: string

      The log level for the entry. Can be either "info", "warning" or "error"

    Returns Promise<void>

    Example

    fin.System.log("info", "An example log message").then(() => console.log('Log info message')).catch(err => console.log(err));
    
  • Monitors a running process. A pid for the process must be included in options.
    A uuid may be optionally provided. If not provided, OpenFin will create a uuid for the new process.

    Parameters

    Returns Promise<Identity>

    Remarks

    If an unused uuid is provided in options, it will be used. If no uuid is provided, OpefinFin will assign a uuid.

    Example

    fin.System.monitorExternalProcess({
    pid: 10208,
    uuid: 'my-external-process', // optional
    listener: function (result) {
    console.log('the exit code', result.exitCode);

    const domainSettings = await fin.System.getDomainSettings();
    // {
    // "rules": [
    // {
    // "match": [
    // "https://openfin.co"
    // ],
    // "options": {

  • Shows the Chromium Developer Tools for the specified window

    Parameters

    • identity: Identity

      This is a object that is defined by the Identity interface

    Returns Promise<void>

    Tutorial

    System.showDeveloperTools

  • Start the crash reporter if not already running.

    Parameters

    Returns Promise<CrashReporterState>

    Remarks

    You can optionally specify diagnosticsMode to have the logs sent to OpenFin on runtime close. (NOTE: diagnosticsMode will turn on verbose logging and disable the sandbox for newly launched renderer processes. See https://developers.openfin.co/of-docs/docs/debugging#diagnostics-mode for more details.)

    Example

    fin.System.startCrashReporter({diagnosticsMode: true}).then(reporter => console.log(reporter)).catch(err => console.log(err));
    
  • Attempt to close an external process. The process will be terminated if it has not closed after the elapsed timeout in milliseconds.

    Note: This method is restricted by default and must be enabled via API security settings.

    Parameters

    Returns Promise<void>

    Example

    fin.System.launchExternalProcess({
    path: "notepad",
    listener: function (result) {
    console.log("The exit code", result.exitCode);
    }
    })
    .then(identity => fin.System.terminateExternalProcess({uuid: identity.uuid, timeout:2000, killTree: false}))
    .then(() => console.log('Terminate the process'))
    .catch(err => console.log(err));
  • Updates Process Logging values: periodic interval and outlier detection entries and interval.

    Parameters

    Returns Promise<void>

    Remarks

    When enabling verbose mode, additional process information is logged to the debug.log:

    1. Periodically process usage (memory, cpu, etc) will be logged for each PID along with the windows, views and iframes that belong to them. The default is every 30 seconds. Updatable by passing the interval option.
    2. When Windows and Views are created or navigated the PID they belong to and their options will be logged.
    3. When Windows and Views are destroyed their last known process usage will be logged.
    4. Whenever an outlier memory usage is detected it will be logged. By default, on an interval of 5 seconds we will collect process usage for all PIDs and when 144 such entries are collected, we will start analyzing the data for any possible outliers in the following entries. The interval and maximum number of entries stored in the running buffer can be updatable by passing the outlierDetection.interval and outlierDetection.entries options.

    Example

    await fin.System.updateProcessLoggingOptions({
    interval: 10,
    outlierDetection: {
    interval: 15,
    entries: 200
    }
    });
  • Update the OpenFin Runtime Proxy settings.

    Parameters

    • options: ProxyConfig

      A config object defined in the ProxyConfig interface

    Returns Promise<void>

    Example

    fin.System.updateProxySettings({proxyAddress:'127.0.0.1', proxyPort:8080, type:'http'})
    .then(() => console.log('Update proxy successfully'))
    .catch(err => console.error(err));
