Numerous issues with Angular Compodoc since v6.4.0-alpha.34

I’m experiencing numerous issues with Angular in newer versions of Storybook. It seems they are all related to Compodoc. These issues include:

• Arrays are interpreted as strings
• Enums are not correctly interpreted
• EventEmitters throw errors

I tracked down the version when this started happening and I found out that these issues started to occur in v6.4.0-alpha.34 (in v6.4.0-alpha.33 everything is fine). I assume it is related to this pull request: #15744

Note: These issues are also still present in latest 6.5.0-alpha.26

Reproduce:

Clone this repository: https://github.com/decline/storybook-angular-issues

There are 3 stories that describe what is going wrong.

See errors in v6.4.0-alpha.34:

yarn && yarn storybook

See it working in v6.4.0-alpha.33:

git checkout 6.4.0-alpha.33
yarn && yarn storybook

As soon as you remove the setCompodocJson(docJson); line in .storybook/preview.js it will also work in v6.4.0-alpha.34, but then you will also lose Compodoc support 😕

I also recorded a video that shows the comparison between the two versions:

@decline it could also be related to this PR which also went out in v6.4.0-alpha.34 #15881

Thanks for tracking this down!

I have looked into #17004 and it is connected to the removal of eval. I have created a PR to fix this but having some problem with tests https://github.com/storybookjs/storybook/pull/17353
