I'm the author of the website mentioned by zebracanevra that does just that.
When a user requests the documentation for a package hosted on npm, a lambda function (Vercel/AWS) runs the analysis process using the TypeScript compiler.
The TS compiler is slow though and this process can take several seconds to finish for packages of medium and larger sizes (you can see the exact time at the bottom of a generated documentation page).
