A CLI tool / Node module you can use to combine your HTML, CSS, and JavaScript code into one file, reducing the number of network requests a client has to make.
- Node ^7.8 (for await/async support)
npm i -g inline-sources
inline-sources entryFile.html outputFile.html
require('inline-sources')('entryFile.html', 'outputFile.html');
The script opens the entry file and looks for any "link"/"script" tags and puts the code directly in the HTML using the "style"/"script" tags respectively. If the linked CSS files have "@import" statements within them, they will be resolved recursively so that the output file is a complete HTML/CSS/JS bundle that does not necessitate further requests to obtain stylesheets and scripts.
Sources starting with 'http(s)://' are obtained using GET requests. Other sources are obtained from the local file system.
