Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (strapi-plugin-responsive-image) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Strapi plugin responsive-image

Custom responsive image formats for https://strapi.io v4 (For strapi v3 use v0.5.0)

How it works

Go to the settings and choose the Responsive image menu
Add/edit the formats
Upload a new media and it will have the new formats automatically generated

Installation

Using npm

npm install --save strapi-plugin-responsive-image
npm run build

Using yarn

yarn add strapi-plugin-responsive-image
yarn build

Setup

We need to override the image manipulation of the upload plugin and use the one from this plugin. So we need to add a strapi-server.js file within the src/extensions/upload/strapi-server.js folder.

e.g For Javascript:

mkdir -p src/extensions/upload/
touch src/extensions/upload/strapi-server.js

Paste the code below in the file.

const imageManipulation = require("strapi-plugin-responsive-image/server/services/image-manipulation");

module.exports = (plugin) => {
  plugin.services["image-manipulation"] = imageManipulation;

  return plugin;
};

For Typescript:

mkdir -p src/extensions/upload/
touch src/extensions/upload/strapi-server.ts

Paste the code below in the file.

const imageManipulation = require("strapi-plugin-responsive-image/server/services/image-manipulation");

export default (plugin) => {
  plugin.services["image-manipulation"] = imageManipulation();

  return plugin;
};

Now when you'll upload a file you'll have the formats of the settings page.

TODO

Better UI/UX, maybe like the settings of the webhooks
Add re-generate button to re-generate all the formats if we change the settings
