I think removing the null is cleaner. Can you check why we have null there? |

Can you rebuild the schema |
|
Just did that, but it didn't produce any changes I could commit. Is there a way to trigger the tests again? |
Great if there are no changes! Before and after, is there any externally observable change? Can you assign a value that could not be assigned before or vice versa? To run the test in your fork, you may need to add a github token. Buf it there are no changes, then we should be good. Let me know and I will review the changes carefully. |

This change makes a difference (#7357 (comment)) but since the schema is not affected, this is ok. Thank you for the pull request. |
|
Thanks for merging and doing the follow up! |
|
Do you have a usual release schedule? I'm just wondering if you can estimate when this fix will make it into a release? Thanks! |
|
We do not and I want to get a few more things into the 5.1 release. I expect a release in the next two weeks, though. |
|
Sounds great, thanks! |

Strict null checking is giving some errors when compiling the docs. For example vega/vega-lite#7352 and another one: Error: buildutils/src/local-repository.ts:113:34 - error TS2345: Argument of type '{ prev_npm: string; prev_yarn: string; pid: number | undefined; }' is not assignable to parameter of type 'JSONObject'. Property 'pid' is incompatible with index signature. Type 'number | undefined' is not assignable to type 'JSONValue'. Type 'undefined' is not assignable to type 'JSONValue'. 113 utils.writeJSONFile(info_file, data); ~~~~ Error: node_modules/vega-lite/build/src/vega.schema.d.ts:34:19 - error TS2344: Type 'null' does not satisfy the constraint 'SignalRef | ExprRef'. 34 value?: Value<null>; ~~~~

* Restrict version of linting packages When refreshing the yarn.lock files, with ^ semver ranges on linters, it upgraded the lint packages to newer versions that had different linting decisions (causing lots of formatting changes). I think upgrading lint to new linting decisions should be a very explicit decision (not just refreshing yarn, but actually updating required versions), since lots of formatting changes can be effected. * Restrict storybook version * Refresh yarn.lock This was done by deleting the lock file and installing fresh. * Fix linting error. This fixes one place where a promise was not handled. * Turn off strict null checking for typedoc. Strict null checking is giving some errors when compiling the docs. For example vega/vega-lite#7352 and another one: Error: buildutils/src/local-repository.ts:113:34 - error TS2345: Argument of type '{ prev_npm: string; prev_yarn: string; pid: number | undefined; }' is not assignable to parameter of type 'JSONObject'.

In the latest 3.0 release, if a single launcher tab is open, it does not have a close X in the tab (since we must have at least one tab open). In master, the close X does appear, but does nothing when clicking on it. After #10516, the 3.0 behavior is restored: if a single launcher tab is open, it does not have an X.

When you consume
TopLevelSpeclikeimport type { TopLevelSpec } from 'vega-lite';in a project withstrictNullChecksset totrue, you'll run into the following error:The problem seems to be that the generic
ESfor theValuetype doesn't includenull. Changing that type toValue<ES extends ExprRef | SignalRef | null = ExprRef | SignalRef | null>fixes it.An alternative would be to remove the
<null>from the code that referencesValuesince the type definition includesExprRef | SignalRefas a default anyway.Let me know which version would make more sense and I'll update the PR.
