javascript keyvalue object

Javascript convert key value string to Object

Let the following "key value string":


I want that string to be converted to Objet or JSON:

{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

Use Object.fromEntries()

A built-in tool that is Use Object.fromEntries() where it states that:
const arr = [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];
const obj = Object.fromEntries(arr);
console.log(obj); // { 0: "a", 1: "b", 2: "c" }

So, the target is to get something like

[ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];



In order to achieve that, we need a small utility:

const parseDescription = function (d)  {
    var a1 = d.split(";");
    var r = => {return f.split("=");});
    return r;

And this is how it executes in a Node REPL:

mihamina@a-onp ~]$ /home/mihamina/Apps/node/bin/node 
Welcome to Node.js v16.17.0.
Type ".help" for more information.
> const parseDescription = function (d)  {
...     var a1 = d.split(";");
...     var r = => {return f.split("=");});
...     return r;
... }
> result=Object.fromEntries(parseDescription("maxRU=5000;database=rktmb_credit;counting=databaseLevel"));
{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

We got what we want.

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href=''" parameter. npm run build --base-href=' did not set the base href in indext.html After looking for a while, I found where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='

Emacs TypeScript Development

Emacs Configuration for Typescript In order to comfortably develop on Node, React or Angular projects with Emacs, TIDE is a good solution. We have TypeScript code highlight (that is the minimum!) and code completion based on the codebase (not only on locally defined and builtins) In order to achieve that: Install Emacs (24+) Install Node Install Typescript (which will provide "tsserver") Install TIDE and some usefull dependencies Configure Emacs to use all those Node is then installed in " /home/mihamina/Apps/node-v12.18.0-linux-x64/bin ": you should add it to your PATH. Installing Typescript is done with: npm install --save typescript @types/browserify After that, "tsserver" will be in " /home/mihamina/node_modules/.bin " Then comes the installation of TIDE: With the Emacs package manager, M-x package-install , install "tide". Do the same for "web-mode", "flycheck", "company" "js2-mode" and "
