Node SASS 5.0.0

[owensgit]

Description

This replaces the Dependabot PR to bump Node SASS to 5.0.0.

A breaking change in Node SASS 5.0.0 requires a minimum Node version 14.5.4.

I updated to Node v14.15.4 and ran the build, it completed without errors 👍 .

However, when I ran npm run start, the following warnings appeared, which may need some investigation when time allows. An issue on the Node repo suggests using the --trace-warnings flag help pin point it.

In DRAFT status as the following warnings still need invesigation.

Build is failing, so even more investigation is needed. Will pick this up when I have time. Otherwise, if anyone else is at a loose end, please feel free 🙂

After some more investigating, it turns out that npm run test and npm run build:test-app both fail because of an error that comes from sass-loader:

ERROR in Module build failed (from /Users/owen/src/canopy/node_modules/sass-loader/dist/cjs.js):
Error: Node Sass version 5.0.0 is incompatible with ^4.0.0.

This is caused by an issue in sass-loader which would not allow versions greater than 4 of node-sass to be used. It has been fixed in sass-loader v10.0.5, however two of our dependencies use older versions as sub dependencies:

@legal-and-general/[email protected] /Users/owen/src/canopy
├─┬ @angular-devkit/[email protected]
│ └── [email protected]
└─┬ @storybook/[email protected]
  └── [email protected]

One approach here could be to manually change these sub dependencies in package-lock.json, although I’d worry about bumping the one in Storybook as it’s two major versions behind.

Alternatively we could stay on node-sass 4.14.1 until sass-loader is updated in both places.

I can't find @angular-devkit/[email protected], have you done an npm install?

In any case, I think the main issue is the storybook package so I would be ok to stay on [email protected] until we update that. Is anyone working on the upgrade that you know of?

You can only really modify transient dependencies in the package-lock if they are within the accepted range, otherwise they get overwritten. So in the case of the angular storybook one its pinned to major version 8 by the caret'^'. This prevents us accidentally mixing incompatible versions, but it does sadly rule out this approach.

i noticed that our angular-devkit dependency is also out of date, I believe the version should reflect the Angular build we are on, e.g. @angular-devkit/[email protected]. Upgrading this seems to fix the tests, but it still has issues with the storybook build.

[andy-polhill]

I raised a separate PR for the angular-devkit upgrade, but I'm not too sure what to do about this one. It may be we have to hold fire until we can finally tackle #35

Excellent, thanks for raising that PR @thatguynamedandy 👍 I'll create an issue to track the update to Node v5.0.0 and close this PR.
