Vue-cli: Support tslint's '--out' option in @vue/cli-plugin-typescript

[jerry88kim]

Version

3.0.1

Node and OS info

Node 10.9.0 / yarn 1.9.4 / MacOS 10.13.6

Steps to reproduce

yarn add @vue/cli-plugin-typescript

vue-cli-service lint --format junit --out tslint.xml

What is expected?

Save tslint's output in file using '--out' option.

What is actually happening?

'tslint.xml' file does not produce.

'--out' option supported in existing tslint(https://palantir.github.io/tslint/usage/cli/) does not work with tslint in @vue/cli-plugin-typescript.

Is the cli lint command even running tslint? Or is it running eslint? I get no errors when running vue-cli-service lint but plenty of tslint errors when running vue-cli-service serve?

If you have installed the eslint plugin as well, lint will use eslint. If you haven't, it will use tslint:

https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-plugin-typescript/index.js#L81-L93

This behaviour isn't really what the README says:

If opted to use TSLint during project creation, vue-cli-service lint will be injected.

I get no errors when running vue-cli-service lint but plenty of tslint errors when running vue-cli-service serve?

tslint is used by the fork-ts-checker plugin if lintOnServe: true is set in the config and a tslint.json is found.

https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-plugin-typescript/index.js#L73

I think we really need to better document this behaviour, but it's unrelated to the current issue.

Please consider opening a separate issue to track improvment of docs for this.

Happy to make a new issue, but where I was going with my question, is like the original issue, I was hoping to be able to provide command line arguments to the lint command, specifically, to change the formatter to the verbose version, because otherwise I can't see which rules to modify in order to customize the tslinting. Is that possible? Or is there a better way?

Well then it's two things:

1. to use tslint with the lint command, uninstall the eslint plugin
2. If you have additional requests for tslint options, we can consider extending this issue to mean: forward all additional args to tslint.

This would be very helpful :)

Now that TSLint is officially deprecated, TSLint support will be fully dropped in the next major version; as for the current major version, no more bug fixes or features will be implemented except for security reasons. So I'm closing this issue now.

Any idea why --out is ignored by the vue cli?

vue-cli-service lint --max-warnings 0 --no-fix --format junit --out lint-junit.xml

The following should produce the results in lint-junit.xml but writes to stdout instead.

Also the options -o or --output-file for the ESLint plugin are ignored and output is on stdout instead of to the file.
