HTTPResource Records

Looking at the example above, we can see that three static files were converted to headers and HTTPResource

records ('d3.min.js', 'favicon.ico', and 'index.html').

Each output header file contains a single HTTPResource , which has the binary equivalent of the file encoded inside it.

For example, for favicon_ico.h we get a 10990 byte long HTTPResource named favicon_ico , shown below:

HTTPResource Collection: resources.h

The tool will also generate a single header file named resources.h, which is the only file that you need to reference in

your sketch.

The resources.h file lists all of the HTTPResource records available, and you can then insert these resources into a

page collection for your sketch, adding them to the AdafruitHTTPServer (https://adafru.it/qoE) individually or as a list.

The tool will attempt to automatically determine the MIME type for the file based on the file extension, selecting from

the list of MIME types supported by FeatherLib.

Using the example from above, we would get the following content in resources.h from D3Graphic:

Looking for files in 'resources'

Converted 'resources/d3.min.js' to '_d3_min_js.h'

Converted 'resources/favicon.ico' to 'favicon_ico.h'

Converted 'resources/index.html' to 'index_html.h'

Wrote resource index to 'resources.h'
