Implement HTTP Webcast Example + Model Params When Null

[davidvonthenen]

Example for doing HTTP Webcast from BBC to LiveClient.

This exposed some params that need to be null'able when certain options are not set.

Walkthrough

The update enhances the solution with two new projects for HTTP and Streaming functionalities. It also modifies various models to support nullable types for improved data handling flexibility. Additionally, a sample application has been added to demonstrate live streaming service integration and transcript processing using Deepgram's API, showcasing practical implementation and usage.

examples/analyze/intent/Program.cs (4)

8-8: The addition of Deepgram.Logger import is appropriate for enhanced logging capabilities in this example.

---

20-20: Setting the logging level to Debug is a good practice for detailed output in development environments. Ensure this is configurable for production use.

---

40-40: Increasing the timeout to 120 seconds is appropriate for operations that might take longer. Ensure this value meets the expected operation times.

Verification successful

---

The timeout of 120 seconds in Program.cs is significantly higher than the default 30 seconds used in other parts of the codebase. This suggests that the operations in Program.cs might require more time, possibly due to their complexity or data intensity. It is recommended to validate this timeout setting based on the actual operation times to ensure it is neither excessive nor insufficient.

Scripts Executed

The following scripts were executed for the analysis:

---

Script:

#!/bin/bash
# Verify that the 120 seconds timeout is sufficient and not excessive for the operations performed.
grep -R "CancelAfter" .

Length of output: 1240

---

---

Script:

#!/bin/bash
# Extract the value of Constants.DefaultRESTTimeout
grep "DefaultRESTTimeout" ./Deepgram/Abstractions/AbstractRestClient.cs

Length of output: 1787

---

---

Script:

#!/bin/bash
# Find the definition of Constants.DefaultRESTTimeout
grep -R "DefaultRESTTimeout =" .

Length of output: 129

---

50-50: Passing the cancelToken to the AnalyzeFile method is a good practice to handle potential long-running operations gracefully.

Deepgram/Factory/HttpClientFactory.cs (1)

19-19: The addition of a logging statement for HttpClient creation is a good practice for monitoring and debugging.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json

Line range hint 27-27: There is a potential issue with a null reference argument when creating an HttpClient. Consider ensuring the httpId is never null before this point.

- var client = sp.GetRequiredService<IHttpClientFactory>().CreateClient(httpId);
+ var client = sp.GetRequiredService<IHttpClientFactory>().CreateClient(httpId ?? HTTPCLIENT_NAME);
