Strapi Provider Firebase Storage

This is a Strapi provider that will upload your files to Firebase Storage.

Installation

npm install strapi-provider-firebase-storage

Note on CORS options

You may run into an issue displaying the image where CORS is blocking it. If that happens open ./config/middwares.js and replace strapi::security with this:

{
  name: "strapi::security",
  config: {
    contentSecurityPolicy: {
      useDefaults: true,
      directives: {
        "connect-src": ["'self'", "https:"],
        "img-src": [
          "'self'",
          "data:",
          "blob:",
          "storage.googleapis.com",
          "dl.airtable.com",
        ],
        "media-src": [
          "'self'",
          "data:",
          "blob:",
          "storage.googleapis.com",
          "dl.airtable.com",
        ],
        upgradeInsecureRequests: null,
      },
    },
  },
},

It will whitelabel images coming from Google Cloud Storage in the CORS settings.

Usage

Here is a sample usage:

1module.exports = ({ env }) => {
2  return {
3    ...
4    upload: {
5      config: {
6        provider: "strapi-provider-firebase-storage",
7        providerOptions: {
8          serviceAccount: require("path/to/my/serviceAccount.json"),
9          // Custom bucket name
10          bucket: env(
11            "STORAGE_BUCKET_URL",
12            "my-bucket-name.appspot.com"
13          ),
14          sortInStorage: true, // true | false
15          debug: false, // true | false
16        },
17      },
18    },
19    ...
20  };
21};

Config Options

Option	Is Required	Default	Notes
serviceAccount	true	none	This is just the path to your service account file
bucket	false	none	If you leave this blank it should go to your default bucket, but I'd recommend putting your default bucket name anyway
sortInStorage	false	true	This will sort files in your firebase storage bucket into folders
debug	false	false	This will just log all the steps to the console

Notes on the sortInStorage option

By default Strapi will just output all the files in the default bucket with no folder structure (even if you make folders in the Strapi admin UI). Strapi also creates variants of files (like iamges ex. thumbnails) so if you upload an image to Strapi you'll actually have like a few variants of it actually uploaded to Firebase.

If you were to look at that in Firebase it would look like total chaos. So what I did was create a couple of functions that will upload your files based on mime type as well as sort all variants of an image under a single folder. If you wanted to do something else with those images (for example create triggers for uploads for specific folders) they will be sorted nicely for you.

Alos be really careful toggling the sortInStorage option. If you have it on, upload some files, then turn it off the delete function could break for the files that were uploaded when it was turned on.
