PreloadScript Object

• type string - Context type where the preload script will be executed. Possible values include frame or service-worker.
• id string - Unique ID of preload script.
• filePath string - Path of the script file. Must be an absolute path.
• matches string[] (optional) - Match patterns for URLs the script runs in. A custom protocol can be used if its scheme is registered as standard with protocol.registerSchemesAsPrivileged. To filter documents served from a non-standard scheme, use includeGlobs or excludeGlobs, which match against the whole URL. If omitted, the script runs for all URLs not excluded by other filters.
• excludeMatches string[] (optional) - Match patterns for URLs the script will not run in.
• includeGlobs string[] (optional) - Glob patterns applied after matches. A URL must also match one of these globs. * matches any sequence of characters and ? matches any single character.
• excludeGlobs string[] (optional) - Glob patterns for URLs the script will not run in.
• matchOriginAsFallback boolean (optional) - Whether a document whose URL has no origin of its own (about:, blob:, data: or filesystem:) is matched by the origin of the frame that created it instead of by its URL. This includes documents with an opaque origin, such as a data: frame or a sandboxed <iframe srcdoc>. For example, an about:blank popup opened by https://example.com/page is matched as https://example.com/. When set, every pattern in matches must have a path of /*. Only applies to frame contexts. Default is false.
