If your site relies on setting/reading cookies, you may experience some issues when interacting with your site within the Makeswift Visual Builder. This is because our builder loads your site within an iframe, so any cookies your site attempts to set are considered as third-party cookies. In order for your site to be able to set cookies that are compatible with the Makeswift Visual Builder, you may need to include certain attributes.

​
Minimum Attributes

In order for a third-party cookie to be set, you’ll need to specify the SameSite=None; and Secure; attributes on your cookie. For example, let’s say your site attempts to set a cookie client-side using document.cookie: 
document.cookie = "myCookie=1234;";
While this may work on your live site, it will not work in the builder because of the third-party restrictions. Let’s update this cookie to use SameSite=None; and Secure;: 
document.cookie = "myCookie=1234; SameSite=None; Secure;";
This will now be able to be set in most browsers, assuming the user has the appropriate browser settings. Similarly, you may be setting cookies in a server response using the Set-Cookie header. For example, you may be using the cookies() API from Next.js: 
import { cookies } from "next/headers";

export async function setCustomCookies() {
  const cookieStore = await cookies();
  cookieStore.set({
    name: "myCookie",
    value: "1234",
  });
}
Again, the same attributes are necessary here: 
import { cookies } from "next/headers";

export async function setCustomCookies() {
  const cookieStore = await cookies();
  cookieStore.set({
    name: "myCookie",
    value: "1234",
    // Adding cross-site attribute below
    sameSite: "none",
    secure: true,
  });
}
If you’re setting a raw Set-Cookie header string on your response header, you can follow the same conventions as the client-side cookie string.

​
Partitioned Cookies (CHIPS)

Nearly all major browsers have plans to fully deprecate third-party cookies in the near future. As a workaround, the Cookies Having Independent Partitioned State (CHIPS) spec was introduced. Partitioned cookies are keyed by both the domain of the third-party site that set them and the top-level site in which they were set. In Makeswift, your site is the one setting the cookie, and the top-level site would be the Visual Builder, app.makeswift.com. This means that any cookies set by your site within the builder are scoped to the builder! To achieve this functionality, simply add a Partitioned; attribute whenever you set your cookies. Using our client-side example from above: 
document.cookie = "myCookie=1234; SameSite=None; Secure; Partitioned;";
And our Next.js cookies() example: 
import { cookies } from "next/headers";

export async function setCustomCookies() {
  const cookieStore = await cookies();
  cookieStore.set({
    name: "myCookie",
    value: "1234",
    sameSite: "none",
    secure: true,
    partitioned: true,
    // ^^^ Cookie will now be partitioned when set on the client
  });
}
Partitioned cookies are currently supported by Chrome and Firefox. Safari support is still in development.

​
Safari

Since Safari still does not currently support partitioned cookies, the recommended way to have full cookie functionality within the builder is to follow our guide to disable cross-site tracking prevention when using our editor.

​
Cookies by other libraries

It’s also possible that you’re using an external package that sets its own cookies. For example, middleware from the next-intl package will attempt to set cookies for detected locales. For such cases, we recommend checking the docs of these tools to see if they allow for cookie attribute configuration. Continuing the next-intl example, we see that their APIs offer customization of their locale detection cookie. If the third-party package you’re using does not permit modifying cookie attributes, you may still be able to patch them retroactively using the Next.js cookies() API (if the cookies are set server-side), or by manually writing cookies with the appropriate attributes client-side. Whenever you make changes to how external packages set cookies, make sure to test that the cookie attribute changes don’t impact the security or functionality of your cookies on your live site.
