Java
Class: ExportManager
ExportManager is the most essential module in order to access actions related to FusionExport like, change the export file quality, set up the file format, etc.
Constructor
The constructor of ExportManager takes a config object that can contain host and port values. These values will be used when connecting to FusionExport Server.
Example
new ExportManager();
Methods
setHostAndPort(String host, int port)
This method takes parameters that contains host and port values. These values will be used when connecting to the FusionExport Server:
Name | Type | Default Value | Description |
---|---|---|---|
host |
String | 127.0.0.1 | The host address which will be used when connecting to FusionExport server |
port |
Integer | 1337 | The port number which will be used when connecting to FusionExport server |
These properties are useful when you are running FusionExport server on the port and host of your choice or running behind a proxy like Nginx. It allows the SDK to send request to the new host and port number where FusionExport is running.
Example
exportManager.setHostAndPort("api.fusionexport.com", 1337);
export(ExportConfig exportConfig, String outputDirPath, Boolean unzip)
This is the most important method from ExportManager module. Based on the configuration provided, this method exports your charts and dashboards to the given format. It returns a promise that resolves to the array filenames of the exported files or gets rejected by an error.

exportAsStream(ExportConfig exportConfig)
You can get exported output as a stream and can work with it. Based on the configuration provided, this method exports your charts and dashboards as a stream.

Class: ExportConfig
ExportConfig class is used to set up all the configs for a single export whether it is a dashboard export, single export or a batch export.
Constructor
This constructor does not take any argument.
Example
new ExportConfig();
Methods
set(String configName, String value)
Takes two argument first one as the key second one as the value. You can find more about the options later on in this guide.
Returns
ExportConfig
: The instance of the exportConfig for method chaining.
Example
exportConfig.set("chartConfig", "./static/chart-config.json");
ExportConfig Options
There are plenty of options which you can configure in ExportConfig. These options essentially help you set quality of the image to define how your chart is going to look like.
chartConfig
Type: String
Sets the configuration of a single chart or multiple charts in an array. This configuration should follow the FusionCharts JSON structure. It accepts, file path of the JSON file where the chart configurations have been stored.
Example

exportConfig.set("quality", "best");
outputFile
Type: String
Sets the output filename template, along with the path. You can write ejs style template for output file names. By default two functions are provided. number(start, end, interval) will resolve to a number respective to the position of the chart config in the chart config array in case of multiple file export. timestamp() will resolve to the current timestamp in unix format.
Example
exportConfig.set("outputFile", "path/to/export--<%= number(2) %>");
templateFilePath

exportConfig.set("templateWidth", "1200");
templateHeight
Type: String | Number
Sets the height of the viewport in which it will get rendered. Throws an exception when the data provided by the user is not a string or when the parsed value of the string is NaN.

// With a string
exportConfig.set("templateHeight", "3000");
templateFormat

event to be triggered
Example
exportConfig.set("maxWaitForCaptureExit", 8000);
outputFileDefinition
Type: String
JS file defining functions or array to resolve output file names. You can write functions which will be called with the current chartConfig, index and the whole chartConfig list and will be called when resolving each filename. If it's an array then the values will be used sequentially. You have to call this functions or array in the outputFile template.
Example
exportConfig.set("outputFileDefinition", "resources/outputFileDefinition.js");
