Coming up next are the manners in which that are accessible for you to begin with PostCSS:

Codepen

Prepos

Swallow

I might want us to examine how to begin utilizing Gulp, the undertaking sprinter. The other two techniques are additionally great, the main con with them is the way that you don’t be able to have control on the modules you need use.

Utilizing THE TASK RUNNER GULP TO INSTALL POSTCSS

To begin, you should have the accompanying introduced:

Node.js

NPM

Git

Stage 1

The initial step is to introduce swallow. You can introduce it by opening terminal running this direction. The – g augmentation implies that we are introducing all inclusive:

npm introduce swallow – g

After effectively introducing swallow, you should set up a swallow venture. You will the need to make a package.json record and add it to your undertaking. You can make it by utilizing npm init order. After this, you at that point introduce the swallow bundle to the undertaking. This is finished by running this direction, npm introduce swallow – spare dev. We utilize the expansion – spare dev with the goal that we can have it spared like a dev reliance.

After effectively following the above advance, open the base of the task you have quite recently made, at that point include another document and name it gulp.js. We should permit this record get to the bundle we introduced previously. We can do that by including var swallow = require(‘gulp’); line on the highest point of the gulp.js document. At long last, you can alternatively introduce modules for swallow. This isn’t obligatory since swallow can utilize npm bundles to get modules.

Stage 2

We have now made our undertaking. Just to ensure that we are in agreement, it would be ideal if you check your undertaking root envelope and ensure that you have the accompanying in it:

Package.json

Gulp.js

Introduced swallow as improvement reliance

Stage 3

We are presently going to experience the fundamental strides to introduce and work with PostCSS. The initial step here will be to go to the root envelope of your venture, at that point make two sub organizers, name one of them tstfoo and the other one src. All CSS documents that are not prepared will go to the src envelope while the ones that have been handled to PostCSS will be put away in the tstfoo organizer.

Stage 4

The subsequent stage will be to introduce a module that will be responsible for dealing with the handling of PostCSS documents. The best module to use for this is the swallow postcss module. To introduce this module, open your terminal and explore to the root envelope of your venture utilizing the cd order, the run this direction;

npm introduce – spare dev swallow postcss

Notice that your root envelope has more sub organizers under the node_modules organizer after effective establishment of the module.

Utilizing a manager of your decision, you would now be able to open the undertaking, at that point open the gulp.js record for altering. We are currently going to make factors that will be utilized to for calling the swallow postcss and swallow modules that we just introduced. To do that, we will add the accompanying code to the record:

var swallow = require(‘gulp’);

var postcss = require(‘gulp-postcss’);

After effectively including the abovementioned and following every one of the means accurately, we are currently ready to make an assignment that will peruse a CSS record, at that point give a yield through PostCSS. Give us a chance to begin doing it by adding these lines of code to the gulp.js record:

Experiencing the bit of code over, the principal line has an undertaking called css whose reason for existing is to have a capacity executed. In the capacity to be executed, we have devices, which is a vacant exhibit right now.

In line four, we determine records that we need prepared. That bit of code essentially implies any records in the scr envelope with the expansion.css. At that point we have the cylinder work which sets PostCSS to utilize the capacity postcss() for execution. We have our exhibit tube here as a contention. This will let PostCSS think about the modules we will utilize. In the last line of code, we are disclosing to PostCSS where to store the handled CSS documents.

Stage 5

Give us a chance to include a module precedent and perceive how it functions. We will include a module called cssnext utilized for empowering future language structure. To do that, as yet pointing at your undertaking envelope, open the terminal and run this direction;

npm introduce cssnext – spare dev

From that point onward, open the swallow document and include the accompanying line at the best:

var cssnext = require(‘cssnext’);

We will likewise need to add the module to our instruments exhibit that was already vacant, your cluster should now resemble this:

var devices = [

cssnext

];

Presently, we will alter the style.css record in our src organizer in the undertaking document to something like this:

.cssnext {

foundation: color(green(- 10%));

}

From that point forward, let us return to the terminal again and run the order swallow css. On the off chance that fruitful, check the new document in the tstfoo envelope and you will see changes, this way;
