<h2>Mini-tutorial</h2>
|
|
|
|
|
|
|
|
|
|
Try a Deno program. This one serves a local directory in HTTP.
|
|
|
|
|
|
|
|
|
|
<pre>
|
2018-12-18 18:13:01 -05:00
|
|
|
alias file_server="deno \
|
2019-01-13 15:52:42 -05:00
|
|
|
https://deno.land/x/http/file_server.ts --allow-net"
|
2019-02-02 18:40:18 -05:00
|
|
|
</pre
|
|
|
|
|
>
|
2018-12-18 18:13:01 -05:00
|
|
|
|
2019-02-02 18:40:18 -05:00
|
|
|
Run it:
|
|
|
|
|
<pre>
|
2018-12-18 18:13:01 -05:00
|
|
|
% file_server .
|
2019-01-13 15:52:42 -05:00
|
|
|
Downloading https://deno.land/x/http/file_server.ts...
|
2018-12-18 18:13:01 -05:00
|
|
|
[...]
|
|
|
|
|
HTTP server listening on http://0.0.0.0:4500/
|
2019-02-02 18:40:18 -05:00
|
|
|
</pre
|
|
|
|
|

|
2018-12-18 18:13:01 -05:00
|
|
|
|

|
|
|
And if you ever want to upgrade to the latest published version:
|
|
|
|
|
<pre>
|
2018-12-18 18:13:01 -05:00
|
|
|
file_server --reload
|

|
|
|
|
<h3>Execution time</h3>
|
|
|
|
|
This shows how much time total it takes to run a few simple deno programs:
|
|
|
|
|
<a href="https://github.com/denoland/deno/blob/master/tests/002_hello.ts"
|
|
|
|
|
>tests/002_hello.ts</a
|
|
|
|
|
>
|
|
|
|
|
and
|
|
|
|
|
<a
|
|
|
|
|
href="https://github.com/denoland/deno/blob/master/tests/003_relative_import.ts"
|
|
|
|
|
>tests/003_relative_import.ts</a
|
|
|
|
|
>. For deno to execute typescript, it must first compile it to JS. A warm
|
|
|
|
|
startup is when deno has a cached JS output already, so it should be fast
|
|
|
|
|
because it bypasses the TS compiler. A cold startup is when deno must
|
|
|
|
|
compile from scratch.
|
|
|
|
|
<div id="exec-time-chart"></div>
|
|
|
|
|
|
|
|
|
|
<h3>Throughput</h3>
|
|
|
|
|
Time it takes to pipe a certain amount of data through Deno.
|
|
|
|
|
<a
|
|
|
|
|
href="https://github.com/denoland/deno/blob/master/tests/echo_server.ts"
|
|
|
|
|
>echo_server.ts</a
|
|
|
|
|
>
|
|
|
|
|
and
|
|
|
|
|
<a href="https://github.com/denoland/deno/blob/master/tests/cat.ts"
|
|
|
|
|
>cat.ts</a
|
|
|
|
|
>
|
|
|
|
|
Smaller is better.

<h3>Req/Sec</h3>
|
|
|
|
|
Tests HTTP server performance. 10 keep-alive connections do as many
|
|
|
|
|
hello-world requests as possible. Bigger is better.
