A utility web app for real-time previewing of structured JSON logs

GitHub Actions 'Release' workflow should ensure `package.json` has correct version

Automating this will reduce human error during the release process, and potentially also avoid manual Pull Requests such as #191

Options:

1. The workflow can check the package.json field to ensure that the tag input (such as v0.1.5-experimental) matches the package.json field (such as 0.1.5)

2. Additionally or alternatively, the workflow can automatically modify this file, commit, and push the related change to origin.

Fix details pane responsive styles for small viewports

Details pane layout is broken on small viewports (width <= 1028px):

Improve perfomrance when ingesting a very large number of lines

The app can become sluggish if ingesting a very large number of lines, such as large time series data or large log dump files.

Potential options:

• Pagination
• Culling very old lines
• ...

JSON `"msg"` fields with newlines are not displayed correctly on summary line

See screenshot where "msg" has an escaped newline character, but the summary line only renders one line:

Open question: Is there a standard NDJSON/JSONL best practice for handling newlines in the message field?

WebSocket client does not automatically attempt reconnecting after terminating

Connection can terminate for various reasons. Under most circumstances, the app should attempt to periodically reconnect the WebSocket, up to a certain limit.

Font glyphs do not work on some browsers

Font glyphs have issues rendering on some browsers, such as some versions of Safari. Explore replacing custom font glyphs with SVG icons.

Shell prompt sometimes left in garbage state after app terminates

Sometimes when using pipes, if the left-most app uses control characters in specific ways, after the app terminates, stdout can be left in a garbage state (shell prompt not fully visible). Shell restart is required to restore it back to functional state. I do not have a screenshot at this time, and root cause is unknown. One option to fix this would be to add a CLI option to disable stdout forwarding by this app, bypassing the issue and ensuring that the environment is always intact.

Scroll-to-bottom feature is inconsistent

Sometimes when pressing the downward arrow button in the bottom right corner, the browser will not stick scrolling to bottom as expected.

This issue reproduces inconsistently and can sometimes cause the "renders 100 messages" Cypress test to be flaky.

Very large JSON objects are split into multiple lines

This happens when process.stdin emits multiple data events for a single JSON line. The app should automatically handle this case and parse the object back into syntactically valid JSON.

Open question: What is the standard NDJSON/JSONL best practice in this problem domain?
