TypeScript file extensions map to incorrect file types

[zsakowitz]

Currently, .ts maps to video/mp2t, .mts maps to model/vnd.mts, and .tsx and .cts aren't in the database.

TypeScript uses these extensions:

• .ts is a standard TypeScript file (currently video/mp2t, should be text/typescript)
• .tsx is a TypeScript + JSX file (should be text/tsx)
• .mts compiles to a .mjs file and always runs as an ES module (currently model/vnd.mts, should be text/typescript)
• .cts compiles to a .cjs file and always runs as a CommonJS module (should be text/typescript)

I think that modifying these would be helpful to the user base and fix issues with static file servers thinking TypeScript files are videos. It would also be nice if .ts could both be video/mp2t and text/typescript, but I'm not sure what the opinion is on that.

Hi @zsakowitz and thank you for your issue. This module only provides a list of mime types that has a property of extensions associated with that mime type. You can find the list of where the data is sourced from in the README and instructions for how to get a new mime type (and thus extensions) added.
