What is a package manager ? Why are they necessary ?

Well we got you covered.

Often while developing an application you need dependencies inorder to prevent reinventing the wheel and focus on whats important.

Here is the necessity of a package manager. It helps install dependencies from their huge libraries which are usually open source.

Here are the most common of all package managers -

1. NPM

This is the most common of all package managers and is often used for installing libraries or modules while building projects with Nodejs, ReactJs or Angular or something similar.

2. Composer

If you are a big PHP fan you always know how this helps get you install libraries like swift mailers to send emails, or install a payment gateway in your project or a framework like Laravel or Symfony.

3. Yarn

This is another similar package manager which is often used side by side of npm when you need two package managers to get job done. Its also used as a standalone option.

4. Brew

Is React Native Garbage ?

Well we shall look into two different scenarios inorder to understand this fully. Scenario 1. Company like Google or Apple who wants to release an app and wants real crazy fast app load, wants better control over hardware and does not much care about the cost of hiring teams of native developers for different platforms. This is the case when one should opt for Native code bases like Java or Swift. Now lets look at our next Scenario. Scenario 2. A startup wants to grow crazy fast. It has cost constraint but wants to reach the consumer base of both web, ios and android. In such a scenario, the startup settles down with a framework like React Native and does not bother if the app loads up a little slow, and serves its purpose of getting to the larger audience faster with a bunch of Javascript Developers. So, nothing is garbage. Its just two different scenarios and different priorities based on Business demand.
