+            if (options.noEmitJs && !options.declaration) {
+                programDiagnostics.add(createCompilerDiagnostic(Diagnostics.Option_0_cannot_be_specified_without_specifying_option_1, "noEmitJs", "declaration"));
+            }
+


you would also want to skip verifyEmitFilePath(emitFileNames.jsFilePath, emitFilesSeen); down below when noEmitJs is true

Kind ping regarding this @sheetalkamat

Should I be adding any specific devs from typescript team to this PR? What's the usual process before a PR lands in the repo ?

I think the name should be --emitDeclarationsOnly instead.

i would say this belongs into Advanced_Options

Advanced_options don't show up as part of --help or in default tsc --init. Doesn't it make sense that the option showed up there? I plan to enable allowJs + emitDeclarationsOnly in another PR which would help with lots of npm projects to auto-generate jsdoc to .d.ts declarations.

Puppeteer is one good example

Because it was failing compilation when doing a “gulp build” with an error.

should work now. that was a @types/node issue.

@mhegazy want to take another pass ?

@niieani - Unfortunately this PR doesn't enable emitting declarations from a JS project. I'll start work on it as soon as this PR lands.

mhegazy · 2018-01-24T23:59:04Z

@DanielRosenwasser and @sheetalkamat any concerns?

niieani · 2018-01-26T09:12:43Z

Thank you @nojvek! Looking forward to the next PR 😊!

nojvek · 2018-01-29T16:13:28Z

@mhegazy @sheetalkamat

// @declaration: true
// @emitDeclarationsOnly: true

For consistency with declaration: true flag, does it make sense to call this new flag emitDeclarationOnly ?

        declaration?: boolean;
        emitDeclarationsOnly?: boolean;
        declarationDir?: string;

It seems the pattern is to use singular *declaration*.

What do you think ?

I can send a rename PR

mhegazy · 2018-01-30T00:04:34Z

humm.. good point.. we can change it to EmitDeclarationOnly
