Using Fresh canary version

Pretend you have a use case where you need to modify your project to use a canary version of Fresh. Or you want to use a slightly different initialization script. This page has you covered.

Canary Fresh in `deno.json`#

Specific commit#

Let’s say you like living life in the fast lane, and want a particular commit. How can you modify your project to no longer use the current release, but instead this one particular commit? Just make the following changes to your deno.json:

     "update": "deno run -A -r https://fresh.deno.dev/update ."
   },
   "imports": {
-    "$fresh/": "https://deno.land/x/fresh@1.2.0/",
+    "$fresh/": "https://raw.githubusercontent.com/denoland/fresh/the-particular-commit-hash-here/",
     "preact": "https://esm.sh/preact@10.22.0",
     "preact/": "https://esm.sh/preact@10.22.0/",

Forked Fresh#

Or what if you have a PR created but it’s not getting merged into main. Don’t worry, you can use the same approach to reference any branch in a fork as well. Here’s an example of referencing a feature in a forked repository that hasn’t been merged yet (at the time of writing this):

     "update": "deno run -A -r https://fresh.deno.dev/update ."
   },
   "imports": {
-    "$fresh/": "https://deno.land/x/fresh@1.2.0/",
+    "$fresh/": "https://raw.githubusercontent.com/deer/fresh/state_in_props/",
     "preact": "https://esm.sh/preact@10.22.0",
     "preact/": "https://esm.sh/preact@10.22.0/",

Creating a new project#

What if you’re getting into open source development, and you’ve of course decided to contribute to the best, freshest project around. Maybe you want to create a test project based on your local changes.

Creating a project from source#

Instead of doing it like this:

deno run -A -r https://fresh.deno.dev/

do it like this:

deno run -A -r path/to/fresh/init.ts

(or wherever your local code lives)

Creating a project from the latest commit#

Of course there’s no reason why you have to check out the Fresh source. You can create a project from the latest commit by combining the techniques on this page like this:

deno run -A -r https://raw.githubusercontent.com/denoland/fresh/main/init.ts
