Restart existing Docker container

Introduction

As a user of the Pocket ID application, I have encountered a frustrating issue that affects the overall user experience. When the frontend startup process is initiated without an internet connection, it takes an excessively long time to complete. This issue not only hampers the normal functioning of the application but also leads to errors in the webUI for Pocket ID settings. In this article, we will delve into the reproduction steps, expected behavior, actual behavior, version, and environment to better understand this issue.

Reproduction Steps

To reproduce this issue, follow these steps:

Restart existing Docker container: When the host does not have an internet connection, restart the existing Docker container. This will trigger the frontend startup process without an internet connection.
Observe the startup process: Monitor the startup process and note the time it takes to complete. You will likely observe that the frontend takes a long time to come up.

Expected Behavior

The expected behavior is that the frontend startup process should not be impacted by internet availability. In other words, the application should start up normally even without an internet connection.

Actual Behavior

However, the actual behavior is that the frontend takes a long time to come up when there is no internet connection. Furthermore, the webUI for Pocket ID settings does not work during this time. But, surprisingly, the SSO (Single Sign-On) still works.

Version and Environment

The version of the application that exhibits this issue is v0.36. The environment in which this issue occurs is a Docker container without an internet connection.

Log Output

When the frontend startup process is initiated without an internet connection, the log output is No response. This indicates that the application is unable to connect to the internet and is stuck in an infinite loop, waiting for a response.

Analysis

After analyzing the reproduction steps, expected behavior, actual behavior, version, and environment, it appears that some non-async process is trying to reach out to the internet and failing to startup for a long time. This is evident from the error logs that constantly display errors related to the update check.

Solution

To resolve this issue, we need to add an option to disable the update check. This will prevent the application from trying to connect to the internet and waiting for a response. By disabling the update check, we can ensure that the frontend startup process completes quickly, even without an internet connection.

Code Snippet

To implement this solution, we need to modify the code to include an option to disable the update check. Here is a code snippet that demonstrates how to achieve this:

// Disable update check option
const disableUpdateCheck = true;

// Update check URL
const updateCheckUrl = 'https://api.github.com/repos/pocket-id/pocket-id/releases/latest';

// Check if update check is disabled
if (disableUpdateCheck) {
  // Do not attempt to connect to the internet
  console.log('Update check is disabled. Skipping...');
} else {
  // Attempt to connect to the internet
  fetch(updateCheckUrl)
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error(error));
}
