How can I create an archive page with all posts on that page?

I want to create a page that consists of all the posts that my website and there is no pagination and other things. When I am trying to create an archive page by naming archive.hbs it’s not creating.

You can create a file: page-archive.hbs (and a page in the Admin section with Page URL: archive).
Inside the page-archive.hbs you can fetch all posts like this:

{{#get "posts" limit="all" order="published_at desc"}}
  {{#foreach posts}}
    <h3 class="title"><a href="{{url}}" class="link">{{title}}</a></h3>
  {{/foreach}}
{{/get}}

How can I make a pagination in that archive page. Like in the homepage i get the link page/2 how can I get it in the archive page?

Oh, I misunderstood, I thought you did not want pagination.
In that case disregard the previous answer.
You can add the following in routes.yaml:

routes:
  /archive/:
    controller: channel
    template: archive
    data: page.archive

Create the archive.hbs file and loop over the posts:

{{#foreach posts}}
  <h2 class="title">
    <a class="link" href="{{url}}">{{title}}</a>
  </h2>
{{/foreach}}

You should be able to paginate over the posts and you can also include the pagination:

{{pagination}}

I have updated the routes.yml file.
My file structure and routes.yml is like this:

When I am opening /archive it’s showing the page not found.
If I am publishing a page inside the admin panel > pages then its opening at /archive but not showing the pagination.

page-archive.hbs

{{!< default}}
{{#get "posts" limit="all" include="tags,authors" order="published_at desc"}}
        {{#foreach posts visibility="all"}}

            {{> "posts"}}

        {{/foreach}}
 {{/get}}

archive.hbs

{{!< default}}
{{#foreach posts}}
  <h2 class="title">
    <a class="link" href="{{url}}">{{title}}</a>
  </h2>
{{/foreach}}

You should delete the page-archive.hbs.
The page in Admin is needed.
For the archive.hbs don’t forget to add {{pagination}} after the foreach.

The page that is rendering at /archive is showing whole different page. It’s showing the post page.
