calculateTokenExpiration

• calculateTokenExpiration(serverExpiration?, jwtToken?): number

• Calculates the token expiration timestamp with built-in safety buffer. Uses a priority-based approach: server expiration first, then JWT expiration, finally fallback duration. Automatically applies a 5-minute safety buffer to prevent token expiry during requests.

  Parameters

  • Optional serverExpiration: string

    ISO string or date string from server response
  • Optional jwtToken: string

    JWT token string to extract expiration from

  Returns number

  Unix timestamp (milliseconds) when the token should be considered expired

calculateTokenIssuedTime

• calculateTokenIssuedTime(jwtToken?): string | number

• Extracts the issued time from a JWT token for token lifecycle tracking. Used to calculate token age and determine refresh timing based on token lifetime.

  Parameters

  • Optional jwtToken: string

    JWT token string to extract issued time from

  Returns string | number

  Unix timestamp in milliseconds if found, empty string if not available or on error

extractJWT

• extractJWT(jwt): JwtPayload

• Safely decodes a JWT token and extracts its payload. Provides error-safe JWT parsing without throwing exceptions on malformed tokens.

  Parameters

  • jwt: string

    JWT token string to decode

  Returns JwtPayload

  Decoded JWT payload object, or null if decoding fails

getItem

• getItem(key): Promise<string>

• Gets an item from the storage.

  Parameters

  • key: string

    The key to get.

  Returns Promise<string>

  • A promise that resolves to the value of the item.

setItem

• setItem(key, value): Promise<void>

• Sets an item in the storage.

  Parameters

  • key: string

    The key to set.
  • value: string

    The value to set.

  Returns Promise<void>

  • A promise that resolves when the item is set.

updatePrefix

• updatePrefix(prefix): void

• Updates the prefix used in storage keys.

  Parameters

  • prefix: string

    The new prefix to use.

  Returns void
