payload-webp

payload-webp

payloadcms/payload plugin for automatic image conversion to webp format.

Getting started

1. Install the package with npm i payload-webp OR yarn add payload-webp
2. Import the plugin to your payload.config.ts:

import webp from "payload-webp";

export default buildConfig({
  ...
  plugins: [
      webp(webpPluginOptions)
  ]
)};

1. After uploading images to your upload-enabled collection new field called webp is added with converted image => webp file meteadata and its sizes. Access webp field with graphql like so:

query {
  allMedia {
    docs {
      url               # url of original file [jpeg/png/webp]
      filesize          # filesize of original file
      webp {
        url             # url of webp processed file [webp]
        filesize        # filesize of webp processed file
        sizes {
          thumbnail {
            width
            height
            url
          }
        }
      }
    }
  }
}

By default webp images are being processed to reduce their filesize as well.

Plugin options

Optionally you can pass JSON with following plugin options to tweak compression or limit conversion to particular mimeTypes or specific upload-enabled collections.

interface WebpPluginOptions {
  /**
   * Which mime types convert to webp.
   * Defaults to: ```["image/jpeg", "image/png", "image/webp"]```
   *
   * ***image/webp** is compressed*
   */
  mimeTypes?: string[];

  /**
   * sharp webp options
   * defaults to:
   * ```
   * {
   *    nearLossless: true,
   *    quality: 50,
   *    force: true,
   * }```
   */
  sharpWebpOptions?: sharp.WebpOptions;

  /**
   * Array of collection slugs that should have images converted to webp.
   * By default all collections with upload property will convert images to webp.
   */
  collections?: CollectionConfig['slug'][];

  /**
   * By default image conversion happens asynchronously in the background for faster UX.
   * By switching this flag hook and following request response will await for the image conversion.
   */
  sync?: boolean;
}

Regenerate Webp images

You can regenerate existing images with following GraphQL mutation:

mutation {
  WebpRegenerate(slug: String!, sort: String) {
    currentFile
    current
    total
  }
}

Arguments

First Header	Second Header
slug	Upload collection slug in camelCase
sort	You can pass the sort parameter to set the direction in which images will be regenerated. Default: createdAt

Fields and subsequent calls

You can use returned fields to show notify of current progress to user. Any subsequent call while regeneration of particular collection is in the progress will not start new regeneration process, but will return current progress.
