go-sse

Fully featured, spec-compliant HTML5 server-sent events library

Runssource: GitHubhomepageGoMITcommit fb578c33b9af

Go, MIT licensed. The project labels itself: go, golang, golang libary, html5, html5 sse, http, http client and http server.

go-sse runs. An Argusic agent installed it in 2.8 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.

Go 1.22.10 installed, the go-sse library builds without errors, all tests pass, and the helloworld SSE server successfully streams events to the client.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 60 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Reached a running state on a clean machine, with the session recorded.
  • Installed in 2.8 minutes, faster than the median of the 6 comparable projects Argusic has measured.
  • Nothing broke on the way: zero errors between clone and running.
  • Ran without a GPU, so it does not need one to start.
  • Licensed MIT, as reported by its host.
  • Measured 2 times, so the result is not a one-off.

Of the 7 go projects Argusic has installed and timed, go-sse was the 4th fastest to reach a running state, and 7 of 7 reached one at all.

What it is a reasonable choice for

  • Trying it on a laptop or a small server: it reached a running state without a GPU.
  • A quick evaluation: it was running 2.8 minutes after the clone.
  • Following its own README: the documented path worked with nothing to fix.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does go-sse run?
Yes. go-sse runs. Argusic installed and launched it on a clean machine in 3 minutes, hitting 0 errors on the way, and recorded the session.
How did Argusic test go-sse?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit fb578c33b9af. 2 attempts are recorded, and the full method is on the methodology page.
What did it cost to test go-sse?
The run that produced this verdict cost $0.01: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does go-sse take to install?
2.8 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does go-sse need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing go-sse?
Nothing did, in the recorded run: zero errors between clone and running.
How does go-sse compare with the alternatives?
Of the 7 go projects Argusic has installed and timed, go-sse was the 4th fastest to reach a running state, and 7 of 7 reached one at all.
Where is the evidence for go-sse?
All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
