swiperjs to set automatically the number of sildes per view

I am creating a photo carousel using swiperJS ref link here.

Here are the params of the swiper:

mySwiper = Swiper('.swiper-container', {
    loop: false,
    speed: 800,
    slidesPerView: 'auto',
    grabCursor: true,
    spaceBetween: 2,
    initialSlide: 0,
    keyboardControl: false,
    resizeReInit: true,
    autoplayDisableOnInteraction: false,
    pagination: '.swiper-pagination',
    paginationClickable: false,
    nextButton: '.swiper-next',
    prevButton: '.swiper-prev'
});

My purpose is to fit as many slides into the view as possible. The photos are of different width and size, some are landscape mode and some are portrait.

Problem: only showing one slide per view.

Goal: fit in as many slides as possible into view.

could somebody help me to achieve this?

Swiper slides are set by default to 100% width in swiper.css:

.swiper-slide {
  ...
  width: 100%;
  height: 100%;
  ...
}

When you initialize swiper with slidesPerView: 'auto', it will not explicitly set the width sizes of the slides to a calculated number (like it would if you define the slides per view to a fixed number) but it will use the existing slide widths. Without any css/inline style changes, these widths will be 100%.

Note that in the example on the swiper website for slidesPerView: 'auto' you can see how they explicitly set the widths of the slides they want to have a different width in css:

.swiper-slide:nth-child(2n) {
      width: 40%;
    }
.swiper-slide:nth-child(3n) {
    width: 20%;
}

So if you want to use the original image widths just set the swiper slide widths to auto:

.swiper-slide {
    width: auto;
}

Code snippet to show how it works:

var swiper = new Swiper('.swiper-container', {
      slidesPerView: 'auto',
      centeredSlides: true,
      spaceBetween: 30,
      pagination: {
        el: '.swiper-pagination',
        clickable: true,
      },
    });
html, body {
  position: relative;
  height: 100%;
}
body {
  background: #eee;
  font-family: Helvetica Neue, Helvetica, Arial, sans-serif;
  font-size: 14px;
  color:#000;
  margin: 0;
  padding: 0;
}
.swiper-container {
  width: 100%;
  height: 100%;
}
.swiper-slide {
  text-align: center;
  font-size: 18px;
  background: #fff;

  /* Center slide text vertically */
  display: -webkit-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
  -webkit-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  align-items: center;
}

/* this is the important part */
.swiper-container .swiper-slide {
  width: auto;
}
