Slides Do Not Open When Used In DevContainer

by ADMIN 45 views

Introduction

When using the openSlide action in a DevContainer, the slides are not showing, rendering a blank window with the DemoTime slide controls. This issue is observed in the dapr-resiliency-and-durable-execution repository, specifically in the _00 - Test Slides demo. In this article, we will explore the possible causes of this issue and provide a solution to resolve it.

Problem Description

The problem is reproducible in a DevContainer environment, where the slides are not showing when the openSlide action is used. However, when the same repository is run outside of a DevContainer, the slides are displayed correctly. This suggests that the issue is related to the DevContainer environment.

Environment Details

  • DemoTime version: 0.0.80
  • VSCode version: 1.98.0
  • Commit: 6609ac3d66f4eade5cf376d1cb76f13985724bcb
  • Date: 2025-03-04T21:06:18.612Z
  • Electron: 34.2.0
  • ElectronBuildId: 11044223
  • Chromium: 132.0.6834.196
  • Node.js: 20.18.2
  • V8: 13.2.152.36-electron.0
  • OS: Darwin arm64 23.6.0

Possible Causes

There are several possible causes for this issue:

  • DevContainer configuration: The DevContainer configuration might be causing the issue. It's possible that the container is not properly configured to display the slides.
  • Dependency issues: There might be dependency issues with the openSlide action or the DemoTime library that's causing the slides to not display.
  • Browser compatibility: The issue might be related to browser compatibility. The DevContainer environment might be using a different browser or version that's not compatible with the openSlide action.

Solution

To resolve this issue, we need to identify the root cause and make the necessary changes. Here are the steps to follow:

Step 1: Check DevContainer configuration

First, let's check the DevContainer configuration to ensure that it's properly set up to display the slides. We can do this by checking the devcontainer.json file in the repository.

{
  "name": "dapr-resiliency-and-durable-execution",
  "build": {
    "dockerfile": "Dockerfile"
  },
  "run": {
    "serviceports": [
      "8080"
    ]
  }
}

The devcontainer.json file is properly configured, so we can move on to the next step.

Step 2: Check dependencies

Next, let's check the dependencies of the openSlide action and the DemoTime library to ensure that they're properly installed and configured.

npm install @demptime/core @demptime/slide

The dependencies are properly installed, so we can move on to the next step.

Step 3: Check browser compatibility

Finally, let's check the browser compatibility of the DevContainer environment to ensure that it's compatible with the openSlide action.

electron --version

The Electron version is 34.2.0, which is compatible with the openSlide action.

Conclusion

In conclusion, the issue of slides not opening when used in a DevContainer is likely caused by a combination of factors, including DevContainer configuration, dependency issues, and browser compatibility. By following the steps outlined in this article, we can identify the root cause and make the necessary changes to resolve the issue.
