Adding custom data

When you already have your users identified within your app, you might want to add their email automatically attached to the bug report. Bugsee provides APIs for setting, getting and clearing the email.

// setting email

// clearing email

Custom events

Events are identified by a string and can have an optional dictionary of parameters that will be stored and passed along with the report.

    // Without any additional parameters

    // ...or with additional custom parameters
    Bugsee.event("payment_processed", {
                    "amount": 125,
                    "currency": "USD"});

Custom traces

Traces may be useful when you want to trace how a specific variable or state changes over time right before the problem happens.

// Manually set value of 15 to property named "credit_balance"
// any time it changes
Bugsee.trace("credit_balance", 15);

User/Session attributes

Besides email, any arbitrary attributes can be attached to the report as well. Issues are searchable by these attributes in the Bugsee dashboard as well.

Note, that each attribute has a limit of 1kB and total size of all attributes must not be more than 25kB
Bugsee.setAttribute("name", "John Doe");
Bugsee.setAttribute("age", 23);
Bugsee.setAttribute("married", false);

Once set, attributes persist until the application is uninstalled from the device. They can be cleared however using the following API.

// Clear a single attribute by name

// .. or clear all of them

File Attachments

Binary files (attachments) can also be added to the report right before it is being sent. The attachment will be available for download right from the issue viewer. Currently both the amount of attachments and their size is limited. Max of 3 attachments, 3MB (size increased from 1MB starting from v3.0.11).

To specify attachments for the report you should provide corresponding handler by passing it into setAttachmentsHandler() method. Your handler will be called each time new report is being assembled. and it will be provided with the Report object that contains the following fields.

Field Type Notes
Report.type String One of 'crash', 'error' or 'bug'
Report.severity Bugsee.Severity One of Low (1), Medium (2), High (3), Critical (4), Blocker (5)

Each attachment can be represented as an in-memory data or a file on disk.

Field Type Notes
fullpath String Full path to the file you want to attach. Set this field when you want to attach file from disk.
data String Actual data of the attachment. Set this field when you want to attach in-memory data
name String Name of the attachment that will be displayed in web dashboard
filename String Name that will be used when attachment data will be downloaded (name for the downloaded from web dashboard file)
Your handler must be asynchronous (decorated with async keyword) to function properly.
async function myAttachmentsHandler(report) {
    const attachments = [];

    // In-memory data attachment
    const accessLogData = await getAccessLogData();
        data: accessLogData,
        name: 'Access log',
        filename: 'access.log'

    // Add error log only for crashes and errors
    if (report.type !== 'bug') {
        // On-disk file attachment
        const fullPath = await getErrorLogPath();
            fullpath: getErrorLogPath,
            name: 'Error log',
            filename: 'error.log'

    return attachments;

// ...

// Call setAttachmentsHandler to register your handler
