undefined variable that equals to a node module


undefined variable that equals to a node module



I try to transpire my file using browserify or webpack.



This is my code:




let rangy = require('rangy')
rangy.init()
const rang = () => rangy



After transpire my code and add in a html page, I try to get rangy in console, but when i type rangy and press enter button, js says:


rangy



Uncaught ReferenceError: rangy is not defined



When i type rang() and press enter, js says:


rang()


undefined



But line 2 runs correctly.



I need to use rangy in script tag of my index.html.


rangy


index.html



How can I do this?



This is my transpired file:




(function(){function r(e,n,t){function o(i,f){if(!n[i]){if(!e[i]){var c="function"==typeof require&&require;if(!f&&c)return c(i,!0);if(u)return u(i,!0);var a=new Error("Cannot find module '"+i+"'");throw a.code="MODULE_NOT_FOUND",a}var p=n[i]={exports:{}};e[i][0].call(p.exports,function(r){var n=e[i][1][r];return o(n||r)},p,p.exports,r,e,n,t)}return n[i].exports}for(var u="function"==typeof require&&require,i=0;i<t.length;i++)o(t[i]);return o}return r})()({1:[function(require,module,exports){


let rangy = require('rangy')
rangy.init()
const rang = () => rangy

},{"rangy":2}],2:[function(require,module,exports){............





cosnt rang = () => rangy Spelling matters in programming.

It's hard to tell from your question if you are using webpack or not, but if you are then the problem you are having is that webpack wraps everything in a function so that all the webpack stuff doesn't interfere with other, external javascript libraries. Could you provide more details on your webpack configuration and which version of webpack you are using?

I use the lastest version of webpack. But result in browserfy and webpack are same.

If you use webpack, and you are ok with randy leaking into the global scope, then just remove let:


randy


let


rangy = require('rangy');
rangy.init();



randy variable will become available in the console.


randy





thanks. it means also I can user window.rangy

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
