A very simple snippet for web-tools to run queries against sql.js database stored in localStorage
(function(DBName) {
var raw_DB = localStorage.getItem(DBName);
if (raw_DB) {
window._db = (function(raw) {
let db = new SQL.Database(JSON.parse(raw));
return {
run: function(sql) {
let data = db.exec(sql);

Converter RGBA() to #HEX color with applying alpha-channel + additional opacity
// converter rgba(r, g, b, a) color to #HEX string without alpha channel,
// with optional applying afterwards opacity ($opacity)
// by default alpha channel for rgba-color is applying against white background,
// but you can change it by setting third argumnet ($background)
@function rgba-to-rgb($rgba, $opacity: 0, $background: #fff) {
@if $opacity > 0 {
@if $opacity < 1 {
$opacity: $opacity * 100
}
@return mix(mix(rgb(red($rgba), green($rgba), blue($rgba)), $background, alpha($rgba) * 100%), rgb(255,255,255), $opacity)
