imageinliner


``bash
npm install -g imageinliner
`

Tool for inlining background data-uri's into css files.


`bash
imageinliner -i style.css -o outputStyle.css
`

To overwrite the input file instead of outputting to a separate file, add the --overwrite flag.

`bash
imageinliner -i style.css --overwrite
`

When referring to images using source root (/some/images) the imageinliner need to know from where to calculate the root path. Use the --rootPath parameter.

`bash
imageinliner -i style.css -o outputStyle.css --rootPath /some/images
`

imageinliner will reformat the css (line breaks and indentations). To preserve compression and output all in one line, pass the --compress flag.

`bash
imageinliner -i style.css -o outputStyle.css --compress
`

Base64 images is somewhat larger than size of image by itself. Inlining files above 10k is not recommended. Best performance can be achieved for smaller files, where the http setup accounts for a large portion of the transfer.

Pass a limiter (in byte) using the --sizeLimit parameter to exclude images above the sizeLimit.

`bash
imageinliner -i style.css -o outputStyle.css --sizeLimit 10240
`

Multiple parameters can be combined
`bash
imageinliner -i style.css -o outputStyle.css --rootPath /some/images --sizeLimit 10240 --compress
`

The imageinliner module can also be used from node.

with file path
`javascript
var inliner = require("imageinliner");

var cssData = inliner.file("style.css", {
maxImageFileSize: 10240,
rootImagePath: "some/directory",
compressOutput: true
});
`

with css string
`javascript
var inliner = require("imageinliner");

var cssData = inliner.css(css, {
maxImageFileSize: 10240,
cssBasePath: "some/directory/css"
rootImagePath: "some/directory",
compressOutput: true
});
