Expo Documentation

Hi! This is what will make Expo actually be useable by people. :)

How to edit

Usually you want to edit the docs in the unversioned directory. If you want your changes to appear right away (instead of waiting for the next sdk release), read on to the next section.

A note about versioning

Expo's SDK is versioned so that apps made on old SDKs are still supported when new SDKs are relased. The website documents previous SDK versions too.

Version names correspond to directory names under versions/.

unversioned is a special version for the next SDK release. devdocs isn't actually an SDK version, it's a special version that corresponds to the "Tool Developer Documentation" website.

Sometimes you want to make an edit in version X and have that edit also be applied in versions Y, Z, ... (say, when you're fixing documentation for an API call that existed in old versions too). You can use the ./scripts/versionpatch.sh utility to apply your git diff in one version in other versions. For example, to update the docs in unversioned then apply it on v8.0.0 and v7.0.0, you'd do the following after editing the docs in unversioned such that it shows up in git diff:

./scripts/versionpatch.sh unversioned v8.0.0 v7.0.0

Any changes in your git diff outside the unversioned directory are ignored so don't worry if you have code changes or such elsewhere.

As a random person

Thanks for helping! :D Make your changes on a fork of this repository or whatever works for you and submit a pull request. We'll take a look and incorporate them!

As an Expo developer

• Make your changes in universe/docs and commit them. Our shipit bot synchronizes the changes to the public expo-docs repository. Changes will automatically be deployed to https://docs.expo.io on deploy. To change the default version, update the version key in docs/package.json (the deploy script will respect this value).

Testing changes locally

Make sure your machine has Docker installed.

Make sure you've run bootstrap docs/ from the root of Universe.

yarn && yarn start

If you get an error try:

cd gatsby
rm -rf node_modules
yarn

from this directory. The site is viewable at http://localhost:8000/versions/unversioned/index.html.

In my case (Brent), I need to go to http://0.0.0.0:8000/versions/unversioned/index.html for hot reloading to work.

If Docker is not available for you, run yarn run start-no-nginx -- the site will be available at http://localhost:8000/versions/<version>/index.html. However, certain redirects won't work, and you'll have to navigate directly to the documentation you want to view.

To add new documentation files, edit the yaml files under gatsby/src/data.
