This guide walks you through the step-by-step process of upgrading a DoneJS 0.9 app to DoneJS 1.
DoneJS 1.0 brings together the latest changes introduced in CanJS 3.0 and StealJS 1.0. This guide explains how to upgrade your DoneJS 0.9 app (which uses CanJS 2.3 and StealJS 0.16) to 1.0.
Pre-migration preparation
Before upgrading to DoneJS 1.0, it’s a good idea to make sure all of your tests are passing, your project builds successfully, and you can deploy your app. This will give you more assurance as you upgrade individual parts of your project.
To make sure tests are passing, run:
donejs test
To confirm that your build is working correctly, run:
donejs build
NODE_ENV=production donejs start
This will create your production build and then start a local server in production mode. If you open localhost:8080 in your browser, you should see the production bundles being loaded in the Network tab of your developer tools.
If you are using donejs deploy to deploy your site to a service like Firebase, make sure it’s working before proceeding.
Additionally, if you are using either donejs build cordova or donejs build nw to create desktop or mobile apps, make sure both of those are working correctly.
There are a few more pages you might use in your normal development workflow that will be helpful during the migration process:
We recommend taking a “bottom up” approach to upgrading your application by focusing on getting each of your components’ test and demo pages working first.
For example, if you have a messages component in src/messages/, the following pages should work correctly:
You should also follow the CanJS 3 pre-migration preparation steps before going through the rest of this guide. The pre-migration section of the CanJS 3 migration guide includes changes you can make to your existing CanJS 2.3 app that will make migrating to CanJS 3 easier.

Install donejs@1
First, upgrade to the latest version of the donejs package on npm:
npm install --global donejs@1
Now any time you create new applications using donejs add app, it will scaffold out a DoneJS 1.0 project.
Use done-serve in static mode
As you do the upgrade, you’ll want to disable SSR so that you can focus on changes to your code. Once all dependencies are up to date you can switch back and everything should work.
To disable SSR, open up your package.json and change your develop script. It will look something like:
done-serve --develop ...
Update it to remove the --develop flag and add the --static flag instead:
done-serve --static ...
Note: removing the --develop flag will disable live-reload. As we upgrade our application, it will be in a broken state most of the time, so live-reload will not work anyway. When we’ve completed the upgrade, we can switch --develop back on.
Once you’ve made these changes, the demo and test pages for your individual components should start to work but your entire test suite may not work quite yet. Don’t worry! Some of the DoneJS dependencies you have installed still expect to use CanJS 2.3; once we’ve upgraded all of those, we’ll start to get the other pages working again.
Note: if you receive an error such as Uncaught Error: You can't have two versions of can-event/batch/batch, you maybe be able to fix the issue by deleting your node_modules folder and running npm install to re-install all of the packages.
Upgrade other DoneJS libraries
Use npm to install the latest versions of the following packages:
At this point, your development.html and src/test.html files should start working. Not all of your tests may pass, but you should be able to load the test page and see results.
Upgrade other dependencies
You may be using other packages that are specifically made to work with CanJS 2.x, like bit-tabs@0.
At this point, you should look for those other dependencies in your package.json and upgrade them, like so:
npm install bit-tabs@1 --save
Once you’ve upgraded CanJS and these ancillary packages, your app should generally work. SSR is still disabled, but the front-end should be okay.
Once this is done, you should be able to start up a server using donejs start. If that works, then re-enable SSR and live-reload in your develop script (remove the --static flag we added earlier):
done-serve --develop ...
If everything seems to work and your tests pass when running donejs test, congratulations! Your project is now on DoneJS 1.0. 🎉
If you run into problems, please refer to the dependency list here and make sure that your version numbers match.

See the CanJS 3 migration guide for instructions on how to migrate CanJS. If you followed the advice above, you will have already gone through the pre-migration steps, so you will only need to follow the minimal migration path steps. We recommend that you also follow the modernized migration path steps as well.
Now is a good time to install the latest versions of any other CanJS packages, including the following:
This will update your
package.jsonto look something like this:Once you’ve made these changes, the demo and test pages for your individual components should start to work but your entire test suite may not work quite yet.

Upgrade to StealJS 1
Refer to the StealJS 1 guide to upgrade StealJS.
Additionally, upgrade to the latest versions of these packages:
This will update your
package.jsonto look something like this:Your package.json’s steal section (which used to be called system) should have this configuration:
This configures Steal to be able to load file types other than JavaScript.
Upgrade other utilities
The last thing is to upgrade everything else that you haven’t already changed. This should include the following:
This will update your
package.jsonto look something like this:Once this is done, you should be able to start up a server using
donejs start. If that works, then re-enable SSR and live-reload in your develop script (remove the--staticflag we added earlier):If everything seems to work and your tests pass when running
