# B2 Remove Prefix Worker

A CloudFlare worker script that removes the `/file/{bucket-name}/` portion of

the URL when access a B2 Bucket.

 - Works with the free tier of CloudFlare and CloudFlare Workers

 - It's still free egress from your B2 bucket

 - No performance penalty, just prettier URLs for your B2 assets

 - Doesn't expose the name of your B2 bucket in the URL

## Why

If you followed [this guide to set up a CloudFlare domain in front of 

Backblaze B2](https://help.backblaze.com/hc/en-us/articles/217666928-Using-Backblaze-B2-with-the-Cloudflare-CDN),

you may have been disappointed by the length of the URL.

For instance, let's say you set up `i.example.com` as a proxied CNAME on

CloudFlare in front of `f001.backblazeb2.com`. Then for you to download a file

called `/test.txt` in the root of the bucket `example-bucket`, the URL would be

`https://i.example.com/file/example-bucket/test.txt`. By putting this Worker

script in front of it, your URL becomes a simple

`https://i.example.com/test.txt`.

## Installation

1. Use 

[wrangler](https://developers.cloudflare.com/workers/tooling/wrangler/install) 

to generate a new app

```sh

wrangler generate myapp https://github.com/phistrom/b2-remove-prefix

```

2. Overwrite the wrangler-generated `wrangler.toml` with a copy of 

`wrangler.toml.example`.

3. Fill in `zone_id`, `account_id`, and `routes` fields as usual in 

`wrangler.toml`

4. Also set the `B2_BUCKET_NAME` under `[vars]` in `wrangler.toml` to your B2 

bucket name

5. Upload to the routes you specified with `wrangler publish` 

**Alternatively**, you could also just copy and paste the code from `index.js` 

into the *Quick Edit* editor in your CloudFlare dashboard. Just be sure to also 

set the `B2_BUCKET_NAME` and `CF_CACHE_TTL` environment variables for this 

Worker by going into its settings.
