  2. Export charts directly from backend without a browser.
  3. Multiple charts can be exported simultaneously with minimal configuration.
  4. Sharing, scheduling etc. can be done.
  5. Export dashboards using user defined template.
  6. Supports statistics logging of all chart exports in a private setup/central remote server.
  7. Save files to FTP or S3.
  8. Export from remote server.
  9. Easy configuration management.

Prerequisites

You need to have node >= 8.0.0 and npm >= 5.0.0 installed in your system to install the CLI.

Usage

After installing, you should have access to fusionexport command. fe is an alias to fusionexport

Or,

fe <options>

Command Line Arguments

Option Alias Default Type Description
--config -e fusioncharts_export.json file, json A JSON file that contains any or all of the CLI options.
--chart-config -c fusioncharts_chart.json file, json A JSON or JS file that contains an array of json objects or just an object, which can be passed to the chart constructor for rendering the chart.

Note: If it's a JS file, the object should be exported.

It can also take multiple files, directory path or glob pattern in a space separated format. For files containing single chart config, it will create a single exported file. For files containing multiple chart config, it will create a directory named after the respective filename that will contain the individual exported file.
--chart-config-options -O {} json JSON object that provides an option to override the chart configuration that has been passed through the chart-config option.

In case of multiple charts, all the charts will be affected.
--input-file -i chart.svg file SVG file that needs to be converted.

It is ignored if chart-config is already provided.

The path will be taken into account if it is provided.
--output-file -o string Output files that need to be generated. A template can also be given that will be resolved for multiple files.

The zipped output will always be named fusioncharts_export.zip.

If an extension is provided with the filename the output type will be inferred from that.

It can also take a directory path; in that case, it should end with a path separator respective to the os.
--output-file-definition -F file JS or JSON file that contains methods and arrays to be used for naming the output files.
--output-as-zip -z bool Exports the output files either as individual files or as a zip.
--type -t png ext Specifies the output file type. This will override any extension provided in the output-file option.
--quality -q better value Quality of the exported files - good, better, best
--width -W 600 value Specifies the chart width.
--height -H 400 value Specifies the chart height.
--callbacks -b fusioncharts_export_callbacks.js file JS file that provides an option for binding custom methods to events fired by the FusionCharts library.
--template -T template.html file JS file that provides an option for binding custom methods to events fired by the FusionCharts library.
--resources -r resources.json file, json JSON file that contains all the resources that will be injected into the template while rendering charts.
--async-capture -a false bool Enable async-capture.
--async-capture-timeout -m 6000 integer Maximum time that system will wait for async-capture event to trigger.
--dashboard-logo -G file Logo path (only for dashboard export)

$ fe -c multiple_charts_config.json -t pdf -o ./exported-charts/

Export entire Dashboard using CLI in PDF format.

To export dashboards using CLI, provide a template file with the layout and supporting static resources (JS, CSS, images, fonts).

The template must contain placeholder elements (preferably divs) for the charts. The chart configuration array must contain the charts with the renderAt attributes that matches the id of the elements stated above.

The resources option is optional and only needed when remote-export-enabled is true. Most resources that are stated in the template in link, script or image tags are found intelligently. If any additional fonts, links present in css or dynamic links in JS is present one has to specify them in resources option.

The format of the resources option is as follows:

{
    "images": [
        "filename.jpg",
        "img/cat.png"
    ],
    "stylesheets": [
        "",
        ""
    ],
    "javascripts": [
        "",
        ""
    ],
    "fonts": [
        "",
        ""
    ]

Output File Naming

The output-file option can take a template which is then resolved using ejs, so that the output filenames can be generated exactly as you wanted it to be.

There are 2 inbuilt functions and you can also provide custom functions in another JS file and pass it in the option output-file-definition

The 2 inbuilt functions are

  1. number(start, end, step): It increments a number from start to end with step as provided. end and step are optional.

  2. timestamp(): It provides the current time is millisecond.

You can provide custom functions or arrays in definition file. Example:

module.exports = {
  caption: (chartConfig, index) => {
    const caption = chartConfig.dataSource.chart.caption;
    return `${index}__${caption}`;
  },
  art: ['S1', 'S2', 'S3', 'S4'],
};

Functions will get 3 arguments, current chart config, index and array of all the chart configs.

Arrays will the iterated one by one and the last one will be repeated if more output files are generated.

Example filenames:

path/to/export--<%= number(1, 100) %>
# path/to/export--1.png 
 
path/to/export--<%= number(2) %>__<%= caption() %>-<%= timestamp() %>
# path/to/export--2__Some Caption-23423438788.png 

Remote Export file saving in FTP & S3

Output files can be saved in FTP and AWS S3 directly.

First you need to provide the credentials in the configuration file. FTP configs are in config/ftp.json and S3 configs are in config/s3.json.

In the output-file options, to upload through FTP specify the filename as

ftp:path/to/export--<%= number(1) %>

to upload files to S3 specify the filename as

s3:export--<%= number(1) %>

Testing

Some preconfigured test configs are present in the uat folder. You can pass those export configuration files to the -e or --config options to run a quick test, or take a look inside it to get an idea how options can be passed in different situations.

Some example commands for running a quick test are

fe -e uat/fusioncharts_export.json
fe -e uat/fusioncharts_export_svg.json
fe -e uat/fusioncharts_export_tmpl.json
fe -e uat/fusioncharts_export_20charts.json
fe -e uat/fusioncharts_export_50charts.json
