Using MathJax and PhantomJS to create SVGs and MathML on server side with minimum overhead.
|
||
|
|
|
||
|
|
MathJax is a great tool! Why not use it on a server side too?
|
||
|
|
|
||
|
|
To avoid loading whole phantomjs and MathJax into memory with every call the service is exposed via HTTP.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ phantomjs main.js &
|
||
|
|
|
||
|
|
loading bench page
|
||
|
|
server started on port 16000
|
||
|
|
you can hit server with http://localhost:16000/?2^n
|
||
|
|
.. or by sending latex source in POST (not url encoded)
|
||
|
|
```
|
||
|
|
|
||
|
|
And then .. curl it up to get back a json array that contains SVG and MathML
|
||
|
|
|
||
|
|
```
|
||
|
|
$ curl localhost:16000/?aa=a^2
|
||
|
|
|
||
|
|
aa=a^2.. 6B query, OK 2393B result, took 15ms.
