+## Trusted Publishing
+
+Trusted publishing is the new npm strategy to allow publishing packages without npm tokens, using OIDC authentication. It currently requires you to set up for each package individually; however, once enabled, no further interaction is required!
+
+### Step 1
+
+- If the package already has a published version on npm, you can skip this step.
+- If the package has never been published, you can publish a "placeholder" package to do the setup process. This CLI tool streamlines this: [setup-npm-trusted-publish](https://github.com/azu/setup-npm-trusted-publish)
+
+### Step 2
+
+- If you're only setting up one package, you can skip this step. Otherwise, the tools below help dramatically when setting up 5+ packages all at once.
+- [open-packages-on-npm](https://github.com/antfu/open-packages-on-npm)
+- [sxzz's userscript](https://github.com/sxzz/userscripts/blob/main/src/npm-trusted-publisher.md)
+
+### Step 3
+
+- Fill in the fields on the package's settings page, similar to this. You will need to authenticate with MFA to save these settings.

+The Vite build setup was the result of several attempts to dual publish ESM and CJS for TanStack projects, while preserving compatibility with all Typescript module resolution options.
 
-## Do I Need This?
+## Do I need dual publishing?
 
 ES Modules (ESM) is the standard for writing JavaScript modules. However, due to the historical dependency on CommonJS (CJS), many ecosystem tools and projects were initially incompatible with ESM. It is becoming exceedingly rare for this to be the case, and I would urge you to consider whether it is necessary to distribute CJS code at all. Sindre Sorhus has a good summary on this issue [here](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
 
+## Do I need this package?
+
+Many alternatives have bene created recently, with the most notable being [tsdown](https://github.com/rolldown/tsdown), built on top of `rolldown`. We will be adopting tsdown for future projects rather than continuing to use our custom Vite setup.

-While this config _will_ work with most frameworks with a Vite adapter, it doesn't mean you _should_ use it for all frameworks, as many have their own build tools which are optimised for their ecosystem. When a framework-specific build tool exists, this should be preferred.
