Function setTokens

setTokens(tokens: AuthTokens): void

Sets authentication tokens and stores them

Implements comprehensive token storage by:

Calculating the exact expiry timestamp for future validation
Storing tokens in memory for fastest access
Persisting tokens in encrypted storage for restarts
Synchronizing token state with the Spotify API module
Scheduling automatic token refresh before expiry

This function serves as the single source of truth for setting tokens across the entire application, ensuring consistent state in all token storage locations.

Parameters

tokens: AuthTokens
Complete set of authentication tokens to store

Returns void

Example

// After receiving tokens from OAuth flow
setTokens({
  accessToken: "new-spotify-access-token",
  refreshToken: "new-spotify-refresh-token",
  expiresIn: 3600
});

Source

export function setTokens(tokens: AuthTokens): void {
  try {
    const { accessToken, refreshToken, expiresIn } = tokens;

    // Calculate expiry timestamp (current time + expires_in duration in seconds)
    const expiryTimestamp = Date.now() + expiresIn * 1000;

    // Store in memory
    setAccessTokenState(accessToken);
    setRefreshTokenState(refreshToken);
    setTokenExpiryState(expiryTimestamp);

    // Store in encrypted persistent storage
    saveEncryptedTokens({
      accessToken,
      refreshToken,
      expiresAt: expiryTimestamp,
    });

    // Set tokens in spotify API module for compatibility
    spotifyApi.setTokens(accessToken, refreshToken, expiresIn);

    // Schedule token refresh if function is set
    if (scheduleTokenRefreshFn) {
      scheduleTokenRefreshFn(expiresIn);
    }

    saveLog("Authentication tokens stored successfully", "DEBUG");
  } catch (error) {
    saveLog(`Failed to store authentication tokens: ${error}`, "ERROR");
  }
}
