How To Run diagrams.net (aka draw.io or drawio) Locally with a Java war File on FreeBSD 13

27 Aug 2022 » howto, diagram, java, graph, graphviz, plaintext, text, tex, latex, visualization, sysadmin, documentation

OS: FreeBSD 13
Shell: csh

From the draw.io project’s Readme file:

The full packaged .war of the client and servlets is built when the project is tagged and available on the releases page.

As of Aug 27, 2022, the latest draw.io version is 20.2.6.

% mkdir drawio
% cd drawio
% fetch https://github.com/jgraph/drawio/releases/download/v20.2.6/draw.war

% file draw.war
draw.war: Zip archive data, at least v1.0 to extract, compression method=store

% unzip draw.war

% pwd

For example, to run it with python3 http.server module on port 8081:

% python3.9 -m http.server 8081

Use a Web browser and open http://localhost:8081 or http://127.0.0.1:8081/ or http://192.168.1.9:8081/.

Alternatively, on this system I could also run it with python 3.8. 1

% python3.8 -m http.server 8081

Note: If you use python2, to use SimpleHTTPServer module, you need to run this command:

% python2 -m SimpleHTTPServer 8081
