A grunt plugin to convert a text file to a file with a data URI in base64
or simple URI encoding. Suitable to convert an HTML file to a data:text/html;charset=utf-8;base64,...
bookmark URI encoded in base64. Or use it to convert a CSV file to a
data:text/csv;charset=utf-8,... URI using basic encodeURIComponent()
encoding. It may also be useful for creating URLs to communicate between web
apps and iOS apps using URI protocol schemes. For converting a .js file to a
javascript: URI, please see the js2uri grunt plugin.
An HTML file containing:
<!DOCTYPE HTML>
<html lang=en><head><title>sample</title><body>content</body><html>might become
data:text/html;charset=utf-8;base64,PCFET0NUWVBFIEhUTUw+CjxodG1sIGxhbmc9ZW4+PGhlYWQ+PHRpdGxlPnNhbXBsZTwvdGl0bGU+PGJvZHk+Y29udGVudDwvYm9keT48aHRtbD4=A CSV file containing:
"Crosby, Stills, Nash & Young", "Déjà Vu"
might become
data:text/csv;charset=utf-8,%22Crosby%2C%20Stills%2C%20Nash%20%26%20Young%22%2C%20%22D%C3%A9j%C3%A0%20Vu%22Install this grunt plugin into a project with:
npm install text2datauri --save-dev. The --save-dev option adds
text2datauri to the devDependencies section of the project package.json
file.
Add the following to the grunt.initConfig section of the project
Gruntfile.js file:
"text2datauri": {
"dist/outputFilename.uri": "dist/lintedAndMinifiedFile.js"
}Edit the values for the dist/output... (destination file) and the
dist/lintedAndMinifiedFile.js source) as appropriate. See
Documenation below for details on additional text2datauri
options.
Below the grunt.initConfig section, load text2datauri as an external task
before using it.
// load external task
grunt.loadNpmTasks("text2datauri");
// default task
grunt.registerTask("default", ["text2datauri"]);The elaborated Gruntfile.js below shows options and defaults relating to
text2datauri.
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
// eslint - Critical eslint rules to disable: no-void, no-script-url
// Example .eslintrc.yml config file--
// env:
// browser: true
// es6: true
// node: true
// extends: eslint:recommended
// rules:
// no-void: 0
// no-script-url: 0
//
// jshint - Critical jshint option: browser & scripturl (allow)
// "jshint": {
// "options": {
// "browser": true,
// "scripturl": true
// }
// },
//
// uglify-js - Note: you may need to 'tune' options for your source
// "uglify": {
// "options": {
// "codegen": {"quote_keys": false}
// "mangle": {"toplevel": true},
// "squeeze": {"conditionals": false, "hoist_vars": true, "sequences": false},
// }
// },
//
// ** text2datauri defaults are shown. Note the file spec uses compact form
"text2datauri": {
"options": {
"encoding": "base64", // "base64" or "uri"; use "uri" for encodeURIComponent()
"mimeType": "text/html", // any string; this is not validated by text2datauri
"protocol": "data:", // any string; this is not validated by text2datauri
"sourceCharset": "utf-8", // "utf-8" or "ascii"; actual format not validated
"targetCharset": "utf-8", // "utf-8" or ""; metadata output is always utf-8
}
}
});
// load external task ("text2datauri" plugin)
grunt.loadNpmTasks("text2datauri");
// default task
grunt.registerTask("default", ["text2datauri"]);
};In lieu of a formal style guide, take care to maintain the existing coding
style. Add unit tests for any new or changed functionality. Lint and test the
code using eslint (preferred) or jshint.
