How to set up HighChart exporter6 min read

This is a node.js application/service that converts Highcharts.JS charts to static image files. It supports PNG, JPEG, SVG, and PDF output; and the input can be either SVG, or JSON-formatted chart options.
The application can be used either as a CLI (Command Line Interface), as an HTTP server, or as a node.js module.

First, make sure you have node.js installed. If you dont have node.js installed, kindly go this link

Hope node.js is installed,now we will install the export server

git clone
cd node-export-server/

Now install the dependent packages

yum install fontconfig freetype freetype-devel fontconfig-devel libstdc++ tar gzip unzip zip bzip2

Create log folder for highchartExport

mkdir -p /home/techrunnr/highchartsExport/logs

Now clean the npm and install phantomjs-prebuilt package

npm cache clean -f

npm install -g phantomjs-prebuilt

cd ..
npm install

[techrunnr@node-server ~]$ cd node-export-server/
[techrunnr@node-server node-export-server]$ ls
bin  build.js  lib  LICENSE  msg  mychart.png  node_modules  package.json  package-lock.json  phantom  testcharts  tests

Lets create to start script for the highchart export server

cd scripts/
/usr/lib/node_modules/highcharts-export-server/bin/cli.js --enableServer 1 --tmpDir /home/techrunnr/highchartsExport --logDest /home/techrunnr/highchartsExport/logs --logLevel 4 &

Stop script for highchart export server

pkill -9 -f node

Give execute permission for both the scripts.

chmod 755
chmod 755

We can test highchart export through one curl command

[root@node-server ~]# curl -H "Content-Type: application/json" -X POST -d '{"infile":{"title": {"text": "Steep Chart"}, "xAxis": {"categories": ["Jan", "Feb", "Mar"]}, "series": [{"data": [29.9, 71.5, 106.4]}]}}' -o mychart.png
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
