TS API Shim

Provides a single API layer to any version of TypeScript. Right now the goal is to first just handle a generic "TS -> JS" conversion.

The goal is:

const ts = require("typescript")
const {createTSShim} = require("typescript-api-shim")
const shim = createTSShim(ts)

const code = `const hello: string = "world"`
const js = shim.toJS(code)

With any version of TypeScript. I'd like to also get consistent error messages, line numbers etc.

typescript-api-shim's Issues

module.exports might be an issue in versions of TypeScript pre v1.4

Heya!

Just had a quick play with this. From the looks of it, node test fails with all versions prior to TS 1.4 with an error like this:

Running tests
Version: ts-08
/home/john/code/github/typescript-api-shim/test.js:26
    console.log(Object.keys(ts).length)
                       ^

TypeError: Cannot convert undefined or null to object

I think this may be because TS 1.4 was the first version of TypeScript which featured a module.exports = ts; statement. Consider TS 1.4:

https://unpkg.com/[email protected]

as compared to

• https://unpkg.com/[email protected]
• https://unpkg.com/[email protected]

I'm guessing the lack of module.exports = ts; will be the reason it chokes?
