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.

Parameters

Name	Type	Default Value	Required	Description
`exportConfig`	`ExportConfig`		Yes	Instance of the `ExportConfig` which will include all export configurations
`outputDirPath`	`String`	`.`	No	Directory where you want to save the exported file.
`unzipFlag`	`Boolean`	`false`	No	This parameter allows you to compress/decompress your output bundle into separate files.

Returns

String[]: It returns an array of strings which contains the array of filenames of the exported files.

Example

exportManager.Export(exportConfig, ".", true);

`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.

Parameters

Name	Type	Required	Description
`exportConfig`	ExportConfig	yes	Instance of the ExportConfig which will include all export configurations

Returns

HashMap: It returns an object with String and ByteArrayOutputStream as HashMap.

Example

HashMap<String, ByteArrayOutputStream> files = em.exportAsStream(config);

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("chartConfig", "resourceschart-config-file.json");

`type`

Type: String

Sets the format of the output file. As of now, it supports png, jpeg, svg and pdf.

Example

exportConfig.set("type", "pdf");

`quality`

Type: String

Sets the quality of the output file. Provide either good, better or best

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`

Type: String

Sets the path of the HTML template used for dashboard export

Example

exportConfig.set("templateFilePath", "resources\template.html");

`template`

Type: String

Send an HTML template in string format to be used for dashboard export

Example

exportConfig.set("template", "<html></html>");

`templateWidth`

Type: String | Number

Sets the width 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 parse value of the string is NaN.

Example

// With a number
exportConfig.set("templateWidth", 1200);

// With a string
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.

Example

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

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

`templateFormat`

Type: String

Sets the format of the PDF pages during a PDF export. This option takes priority over templateWidth and templateHeight. Throws an exception when the data provided by the user is not a string or when the format is not in the supported set. The available options are:

Letter: 8.5in x 11in
Legal: 8.5in x 14in
Tabloid: 11in x 17in
Ledger: 17in x 11in
A0: 33.1in x 46.8in
A1: 23.4in x 33.1in
A2: 16.5in x 23.4in
A3: 11.7in x 16.5in
A4: 8.27in x 11.7in
A5: 5.83in x 8.27in

Example

exportConfig.set("templateFormat", "A4");

`headerEnabled`

Type: Boolean

This enables header in the exported PDF file. When the value of this property is set to true, the following components will be added in the header automatically:

title : Left aligned
url : Right aligned

Please keep in mind that this property should be used while exporting to PDF only.

Example

exportConfig.set('headerEnabled', true);

`footerEnabled`

Type: Boolean

This enables footers in the exported PDF file. When the value of this property is set to true, the following components will be added in the header automatically:

pageNumber : Left aligned
date : Right aligned

Please keep in mind that this property should be used while exporting to PDF only.

Example

exportConfig.set('footerEnabled', true);

`headerComponents` / `footerComponents`

Type: String

These properties will allow you to configure the components which you want to show in the header and footer respectively. As of now, the five components are supported in both header and footer: title, url, date, pageNumber and logo. All the properties will have the following attributes to configure:

Attributes	Type	Description
`position`	String	Will accept values like `left` and `right` which are case-insensitive.
`style`	String	Style defined in CSS string
`format`	String	Only applicable for `pageNumber`. It will accept two keywords, `currentPage` and `totalPages`.
`src`	String	Only applicable for `logo`. It will accept aboslute URL of the logo file

Please keep in mind that this property should be used while exporting to PDF only.

Example

exportConfig.set('headerComponents', "{ date: { position: 'left', style: '' }"});

`headerStyle` / `footerStyle`

Type: String

The style defined here will be set to all the components provided in either the header or footer as a default. You have to provide style in the CSS string format just like the same way you define an inline style.

Example

exportConfig.set('headerStyle', "font-family: 'Source Sans Pro', colour:'#000';");

`orientation`

Type: String

This property will accept portrait or landscape as values. As the name suggests, it will set the orientation of the page. By default the value will be portrait.

Example

exportConfig.set('orientation', 'landscape');

`pageMargin`

Type: String | Object

It will add margins on the page layout. It will accept both string and object. In case of string, margins will get applied on all four sides. In case of object top, right, bottom, left are the properties. Units for providing margins are:

px - pixel
in - inch
cm - centimeter
mm - millimeter

Example

exportConfig.set('margin', '10cm');
exportConfig.set('margin', "{ top: '10px', right: '20px'}");

`resourceFilePath`

Type: String

JSON file having the dependencies of the template when templateFilePath is provided. basePath denotes the base path of the project no local resource should be present outside this directory. include takes one or more glob to specify which files to send to the server. exclude take sone or more glob to specify which files should be excluded.

Example

exportConfig.set("resourceFilePath", "resources\resource.json");

An example of resource.json is shown below:

{
   "basePath": "../src/",
   "include": ["**/*.js"],
   "exlcude": [".env"]
}

`callbackFilePath`

Type: String

Sets the path for a JavaScript file that would be injected at the bottom of the page for each export

Example

exportConfig.set("callbackFilePath", "resourcescallback.js");

`asyncCapture`

Type: Boolean

Is set if the export process waits for the CAPTURE_EXIT event

Example

exportConfig.set("asyncCapture", true);

`maxWaitForCaptureExit`

Type: Integer

Sets the maximum time FusionExport waits for the CAPTURE_EXIT 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");

`inputSVG`

Type: String

This option is useful to export your SVG files to the file formats supported by FusionExport. It accepts file path of the SVG in string format.
