GraalJS and ES4X do not run TypeScript directly, the engine is pure ES2019, which means it still needs a compilation step. You can use something like:
tsconfig.json
:
{
"compilerOptions": {
"outDir": "dist",
"sourceMap": true,
"noImplicitAny": true,
"module": "commonjs",
"target": "es5",
"allowJs": true
}
}
package.json
:
{
"name": "my-tsproject",
"main": "dist/index.js",
"scripts": {
"prestart": "tsc",
"start": "my-tsproject"
},
"devDependencies": {
"typescript": "^3.2.2",
}
}
So when you run your application using the build tool, it precompiles your TS to JS and then invokes the normal application.
