It&#8217;s then converted into a series of characters that are ideal for use as keys in a key\/value object. The great thing about doing things this way is that the ID&#8217;s can be turned back into human readable times\/dates or even unix timestamps quite easily. Another benefit of these lexographic ID&#8217;s is that they are ordered.<\/p>\n<p>If for example a random string was chosen as the key, after a few entries to the database you might notice that things are being thrown in without any consideration for the order in which they were added. This might not be an issue in your specific use-case, but it can make trawling through the database later on a bit of a pain, especially if it starts to get pretty big.<\/p>\n<p>With the Firebase ID&#8217;s generated from a timestamp and outputted in a lexographic string of characters, we can see that any data added to the database using these ID&#8217;s will be added in a sequential order. This makes for a much neater appearance and makes reading the database much more effecient, as the most recently added data is always at the bottom.<\/p>\n<p>Anyway. Enough waffling on.<\/p>\n<p>Here&#8217;s a really handy little tool I found by a developer called <a href=\"https:\/\/gist.github.com\/mikelehen\">mikelehen<\/a> on GitHub to generate these ID&#8217;s for use in your own projects. I hope you find it as handy as I regularly do. \ud83d\ude42<\/p>\n<\/div><\/section><\/p><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_fifth-0aa7055fe62c3622faec82866afbaeb2\">\n.flex_column.av-av_one_fifth-0aa7055fe62c3622faec82866afbaeb2{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_fifth-0aa7055fe62c3622faec82866afbaeb2 av_one_fifth  avia-builder-el-5  el_after_av_three_fifth  el_before_av_one_fourth  flex_column_div av-zero-column-padding  '     ><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_fourth-6126cab7d8fab8d08143dd2dacdf673c\">\n.flex_column.av-av_one_fourth-6126cab7d8fab8d08143dd2dacdf673c{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_fourth-6126cab7d8fab8d08143dd2dacdf673c av_one_fourth  avia-builder-el-6  el_after_av_one_fifth  el_before_av_one_half  first flex_column_div av-zero-column-padding  column-top-margin'     ><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_half-0aa7055fe62c3622faec82866afbaeb2\">\n.flex_column.av-av_one_half-0aa7055fe62c3622faec82866afbaeb2{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_half-0aa7055fe62c3622faec82866afbaeb2 av_one_half  avia-builder-el-7  el_after_av_one_fourth  el_before_av_one_fourth  flex_column_div av-zero-column-padding  column-top-margin'     ><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_fourth-0aa7055fe62c3622faec82866afbaeb2\">\n.flex_column.av-av_one_fourth-0aa7055fe62c3622faec82866afbaeb2{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_fourth-0aa7055fe62c3622faec82866afbaeb2 av_one_fourth  avia-builder-el-9  el_after_av_one_half  el_before_av_one_fifth  flex_column_div av-zero-column-padding  column-top-margin'     ><\/div><\/p>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_fifth-6126cab7d8fab8d08143dd2dacdf673c\">\n.flex_column.av-av_one_fifth-6126cab7d8fab8d08143dd2dacdf673c{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_fifth-6126cab7d8fab8d08143dd2dacdf673c av_one_fifth  avia-builder-el-10  el_after_av_one_fourth  el_before_av_three_fifth  first flex_column_div av-zero-column-padding  column-top-margin'     ><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_three_fifth-0aa7055fe62c3622faec82866afbaeb2\">\n.flex_column.av-av_three_fifth-0aa7055fe62c3622faec82866afbaeb2{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_three_fifth-0aa7055fe62c3622faec82866afbaeb2 av_three_fifth  avia-builder-el-11  el_after_av_one_fifth  el_before_av_one_fifth  flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Hit the &#8220;Generate&#8221; button above and the script will make a new unique ID for you, based on the current timestamp.
