A VueJS component to show a graphical vizualization of a PostgreSQL execution plan.
See Demo .
Disclaimer
This project is a rewrite of the excellent Postgres Explain Visualizer (pev) . Kudos go to Alex Tatiyants .
The pev project was initialy written in early 2016 but seems to be abandonned since then. There was no activity at all for more than 3 years and counting though there are several issues open and relevant pull requests pending.
The current project has several goals:
- isolate the plan view component and its dependencies in order to use it in any web app with for example the ability to load a plan without requiring any copy-paste from the user,
- make it work with recent version of JS frameworks,
- upgrade Bootstrap to a more recent version,
- use VueJS just for a matter of taste,
- maintain the project to match upgrades in PostgreSQL.
Usage
PEV2 is intended to be used as VueJS component.
Install it:
npm install pev2
Declare the PEV2
component and use it:
import pev2 from "pev2";
new Vue({
el: "#app",
data: function() {
return {
plan: plan,
query: query
};
},
components: {
pev2: pev2
}
});
Then add the PEV2
component to your template:
<div id="app"> <pev2 :plan-source="plan" :plan-query="query"></pev2> </div>
PEV2
requires Bootstrap (CSS)
and FontAwesome
to work so don't forget to
add the following in you header (or load them with your favorite bundler).
<link href="https://unpkg.com/bootstrap@4.3.1/dist/css/bootstrap.min.css" rel="stylesheet" /> <link href="https://unpkg.com/font-awesome@4.7.0/css/font-awesome.css" rel="stylesheet" />
