[ontoneio]

🐛 Bug Report

In the /utilities/template-helper.js file there is an import by the name of InlineTemplateDirective which comes from the @microsoft/fast-element package that throws an error because it doesn't exist. InlineTemplateDirective is also not found in the documentation for @microsoft/fast-element

💻 Repro or Code Sample

1. Use import { InlineTemplateDirective } from "@microsoft/fast-element" in a javascript file node.js dev environment
2. Look for error: Module '"@microsoft/fast-element"' has no exported member 'InlineTemplateDirective'.
3. Inspect documentation to verify 'InlineTemplateDirective' is not exported from package. @microsoft/fast-element

🤔 Expected Behavior

Import doesn't throw typescript error and documentation on website shows type or method with this name.

😯 Current Behavior

No access to InlineTemplateDirective import

error message: Module '"@microsoft/fast-element"' has no exported member 'InlineTemplateDirective'.

💁 Possible Solution

Update the documentation and template-helpers.js file

Thanks @ontoneio - Which version are you on of Fast Element? I'll check FE1, but if I recall that was added for the latest beta (which won't reflect yet in the docs).

Hi @chrisdholt ,

Thanks for the quick response. I am using @microsoft/fast-element": "1.12.0 currently
Seems to be latest one. Published 9 months ago?

Yep - The directive is in that specific version though, it's only in the Beta as part of the v2 release. I am looking to propose promoting that to stable soon-ish. With that said, I'm not sure what it would take to backport that off the top of my head.

If it helps the InlineTemplateDirective is being used in this function:

export function staticallyCompose<TSource = any, TParent = any>(
    item: StaticallyComposableHTML<TSource, TParent>
): CaptureType<TSource, TParent> {
    if (!item) {
        return InlineTemplateDirective.empty;
    }
    if (typeof item === "string") {
        return new InlineTemplateDirective(item);
    }
    if ("inline" in item) {
        return item.inline();
    }
    return item;
}

I'm not exactly sure what this function accomplishes, but if I can replace it's functionality I think I will be alright.
So any insight on this function would be greatly helpful.

Looks like this is solved in v2, I'll close this for now, let us know after launch of @microsoft/fast-element v2 (coming very soon) if this is still an issue.
