BrowserContext
Type Alias: BrowserContext
type BrowserContext = {
locale?: string;
timezone?: string;
userAgent: string;
viewport?: {
height: number;
width: number;
};
};Defined in: types.ts:86
Browser-context fingerprint settings — what "browser" the SDK pretends to be when talking to Snap.
Remarks
userAgent is REQUIRED to make consumers think about UA hygiene up front.
If every @snapcap/native consumer defaulted to the same UA, Snap's
anti-fraud could detect "this UA + Node TLS fingerprint" as a snapcap
consumer. Pass a recent, realistic UA from a real browser; for multi-tenant
runners, pass a DIFFERENT UA per client (a JSON tenant-config file is the
natural shape — username, password, and browser fingerprint per tenant).
Other fields are optional but recommended for diversity in multi-tenant deployments — match each tenant's locale, viewport, and timezone to whatever real device they'd plausibly be using.
Example
const browser: BrowserContext = {
userAgent:
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/147.0.0.0 Safari/537.36",
locale: "en-US",
viewport: { width: 1440, height: 900 },
timezone: "America/Los_Angeles",
