Release 4.10.0

jsreport 4.10.0 is here and brings several new features for PDF as well as for office recipes.

PDF compression

The pdf-utils extension now supports enabling PDF compression.

The compression algorithm performs several optimization steps, such as converting images to JPEG or improving PDF structures. This can dramatically decrease the final PDF size. The pdf stock showcase PDF size, for example, drops from 2851 kB to 690 kB with compression enabled.

XLSX dynamic cells

The most complex task in this release was providing support for rendering dynamic cells in the XLSX recipe. This means you can pass to the each loop matrix of cells, and it takes care of rendering the dynamic table based on your input.

If you type handlebars into the Excel cell like this

{{#each cells=items}}{{this}}{{/each}}

and provide the following input data

{
  "items": [
    ["Name", "Lastname", "Score"],
    ["Boris", "Matos", 50]
    ["Alexander", "Smith", 32],
    ["John", "Doe", 25]
  ]
}

The generated cells will look like this

This opens new options for your Excel structures, because you can prepare the cells definition in a dynamic way using extra helper and js code.

Conclusion

The jsreport 4.10.0 brings nice improvements, and we are already working on the next 4.11.0. Stay tuned.
