chore(build): Bump typescript to version 3.6.4 #27
Conversation
|
Note: You should avoid upgrading to TS compiler 3.7.x due to: microsoft/TypeScript#33939 |
|
cc: @jasongrout, who is usually interested in the compiler version |
|
Will this change cause builds by consumers to fail if they use an older version of TS? |
|
@vidartf I don't believe so - unfortunately the same is not true of 3.7.x |

Could this be resolved by adding a dev dependency on @types/node?

I don't think so as its not a NodeJS API "thing" (its a global "window"/"this" thing).

I believe that is a different one to the "window.setImmediate" that lumino is using (the v8 JS runtime one)

(IOW timers.setImmediate vs GLOBAL.setImmediate)

As the typing of schedule/unschedule is not exported, it should suffice to ensure that it compiles, so v12 seems reasonable.

no luck (after testing) and visually inspecting the NodeJS typings its declared in the "timers" module and not globally.
There is a @types/setimmediate which should work - but do you want to go down that road?
At some point you might want a "platform" test:
declare const process: any;
// @ts-ignore
export const root: any = new Function("return this;")(); // Prevent bundlers from messing with "this"
export const isBrowser: boolean = typeof window !== "undefined" && root === window;
export const isNode: boolean = typeof process !== "undefined" && process.versions != null && process.versions.node != null;
export const isTravis: boolean = isNode && process.env != null && process.env.TRAVIS != null;
See: https://github.com/hpcc-systems/Visualization/blob/master/packages/util/src/platform.ts
And will be able to add TypeScript guards for things like setImmediate.
Its still pretty tricky getting a single TypeScript package to "just work" for Node and Browser especially when you get into fetch polyfills and the like...

@GordonSmith Did you see my link to the global.d.ts file? Also, did you add the types dependency to tsconfig.json's types field?

I see that now - pushed new version with suggested change.

I just did a diff of the generated files - the only potential issue I see is the use of the "correct" types in FWIW I have not used these types in my other projects (which have had no issues with older TSC versions). |

I just rebased and see that now (I suspect I just visually missed it before as polling wasn't in my original branch). I see that "notebooks" is on 3.7.2 should this also be 3.6.4? |
|
What is notebooks and should it be in lumino? |
Take it up with @ellisonbg #8 (it is just some maintainer code to discuss code in the datastore package, but I would argue it should be a gist instead). |
|
If it (notebooks) doesn't make it into the npm tar file, then its really up to you folks (I can't say I even noticed it was there). |
it doesn't. (or rather, if it did, it would only make it into its own tar file, as each package is separated) |
