[TypeScript][Node] async promises and imports

[kpturner]

PR checklist

• Read the contribution guidelines.
• Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\.
• Filed the PR against the correct branch: master, 3.4.x, 4.0.x. Default: master.
• Copied the technical committee to review the pull request if your PR is targeting a particular programming language.

Description of the PR

Small modifications to the typescript-node mustache template to ensure that the result will transpile.

Update samples via bffca05. Let's see if all the tests pass

[kpturner]

Blimey do they always take this long to start?

[wing328]

Not sure why the Travis job was omitted but local test result looks good:

Will this now be part of version 3 or 4 or both? When will I be safe to reinstall with Homebrew for example?

[wing328]

This is included in the 4.x. Please refer to #1790 on how to brew install the latest master.

[kpturner]

OK I did that and ended up with 4.0.0-beta but that doesn't contain this fix?

[macjohnny]

@kpturner you need to adapt this file: wing328/homebrew-core@6e809df#diff-7212f3680bef582a293d6249adbf98c3R8

[kpturner]

But there is no Formula/openapi-generator.rb in master?

[macjohnny]

I corrected my comment

[kpturner]

When I checked out git checkout openapi-generator-4.0.0-beta it already contained the code that you suggested I change so unfortunately I am still no further ahead. The only way I seem to be able to run with this fixed is from my original maven build.

[macjohnny]

you need to change the url from https://search.maven.org/remotecontent?filepath=org/openapitools/openapi-generator-cli/4.0.0-beta/openapi-generator-cli-4.0.0-beta.jar to https://oss.sonatype.org/content/repositories/snapshots/org/openapitools/openapi-generator-cli/4.0.0-SNAPSHOT/openapi-generator-cli-4.0.0-20190321.151032-428.jar

[kpturner]

OK - and I guess the sha256 also needs to change?
