<h2>Getting started</h2>
|
|
|
|
|
|
2018-12-18 18:13:01 -05:00
|
|
|
<p>Install Deno into ~/.deno/bin
|
|
|
|
|
<pre>
|
|
|
|
|
curl -L https://deno.land/x/install/install.py | python
|
|
|
|
|
export PATH=$HOME/.deno/bin:$PATH
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
Try a Deno program. Install by bash alias.
|
|
|
|
|
This one serves a local directory in HTTP.
|
|
|
|
|
<pre>
|
|
|
|
|
alias file_server="deno \
|
|
|
|
|
https://deno.land/x/net/file_server.ts --allow-net"
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
Run it:
|
|
|
|
|
<pre>
|
|
|
|
|
% file_server .
|
|
|
|
|
Downloading https://deno.land/x/net/file_server.ts...
|
|
|
|
|
[...]
|
|
|
|
|
HTTP server listening on http://0.0.0.0:4500/
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
And if you ever want to upgrade to the latest published version:
|
|
|
|
|
<pre>
|
|
|
|
|
file_server --reload
|
|
|
|
|
</pre>

<h3>Execution time</h3>
|
2018-10-18 06:23:26 -04:00
|
|
|
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.
|
|
|
|

|
<h3>Throughput</h3>
|
2018-12-13 16:28:49 -05:00
|
|
|
Time it takes to pipe a certain amount of data through Deno.

<a href="https://github.com/denoland/deno/blob/master/tests/cat.ts">cat.ts</a>
|
|
|
|
|
Smaller is better.

<h3>Req/Sec</h3>

2018-12-13 16:28:49 -05:00
|
|
|
Tests HTTP server performance. 10 keep-alive connections
|
|
|
|
|
do as many hello-world requests as possible. Bigger is better.
