@prismicio/client v7 Migration Guide

Overview

This is a guide for upgrading a project that uses @prismicio/client v6 and/or @prismicio/helpers v2 and/or @prismicio/types v0.

@prismicio/client v7 combines all the above into one package, offering a leaner API with a smaller footprint on your project. Because of that, @prismicio/helpers and @prismicio/types are now considered deprecated. The following instructions walk you through upgrading to the updated package.

Benefits of upgrading

  • One single package now covers core Prismic usage (compared to 3 required before)
  • Deprecated APIs from @prismcio/client v5 and v6 were removed
  • Deprecated APIs from @prismicio/helpers v2 were removed
  • Deprecated APIs from @prismicio/types v0 were removed
  • Improved code-splitting and tree shaking

Update packages in package.json

Update your package.json to use the latest version of @prismicio/client.

package.json
Copy
{
  "dependencies": {
    "@prismicio/client": "^7.0.0"
  }
}

Remove @prismicio/helpers and @prismicio/types from your package.json if they were being used. @prismicio/client v7 includes all functionality previously provided by @prismicio/helpers and @prismicio/types.

package.json
Copy
  {
    "dependencies": {


    }
  }

Update your installed packages with npm.

Copy
npm install

Handling breaking changes

The following changes are required when upgrading to @prismicio/client v7.

Replace @prismicio/helpers imports with @prismicio/client

Replace imports for @prismicio/helpers with @prismicio/client. As a convention, all code examples will use import * as prismic when importing @prismicio/client, but this can be modified depending on your preferences.

Copy

 import * as prismic from "@prismicio/client";

If you were using the previous import * as prismicH convention with @prismicio/helpers and switched to the new one, don’t forget to update old references.

Copy

 prismic.asDate(document.data.timestamp);

Replace @prismicio/types imports with @prismicio/client

Replace imports for @prismicio/types with @prismicio/client. As a convention, all code examples will use import * as prismic when importing @prismicio/client, but this can be modified depending on your preferences.

Copy

 import * as prismic from "@prismicio/client";

If you were using the previous import * as prismicT convention with @prismicio/types and switched to the new one, don’t forget to update old references.

Copy

 let page: prismic.PrismicDocument;

Migrate from removed deprecated APIs

APIs that were deprecated in @prismicio/client v5 and v6 were removed. If you didn’t migrate from them previously, you now need to.

Copy

 prismic.getRepositoryEndpoint();




 prismic.filter;


 client.get();

// For `.get` and any other query methods

 client.get({ filters: ... });

// For `.get` and any other query methods


 client.get({ orderings: [{ field: "my.product.price", direction: "desc" }] };


 client.graphQLFetch();

Similarly, APIs that were deprecated in @prismicio/helpers v2 were removed. If you didn’t migrate from them previously, you now need to.

Copy

 prismic.Element;

Finally, APIs that were deprecated in @prismicio/types v0 were also removed. If you didn’t migrate from them previously, you now need to.

Copy

 prismic.ContentRelationshipField;


 prismic.FilledContentRelationshipField;

New features

Previously, @prismicio/helpers v2 helper functions accepted options as positional parameters:

Copy
asSomething(field, option1, option2, ..., optionN)

To standardize and help our API grow better, we have collected those options as named parameters in an options object:

Copy
asSomething(field, options)

While the old helper functions signatures will still work with @prismicio/client v7, they are now considered deprecated and will be removed in a future major.

The following steps are optional but recommended.

Migrate asLink() calls to the new signature

If you were using asLink() with a link resolver, you can convert it to the new signature.

Copy

 prismic.asLink(field, { linkResolver })

Migrate asHTML() calls to the new signature

If you were using asHTML() with a link resolver or a rich text serializer, you can convert it to the new signature.

Copy

 prismic.asHTML(field, { linkResolver })


 prismic.asHTML(field, { serializer })


 prismic.asHTML(field, { linkResolver, serializer })

Migrate asText() calls to the new signature

If you were using asText() with a custom separator, you can convert it to the new signature.

Copy

 prismic.asText(field, { separator })
