Typescript

tedi tries to give a new approach about how we write web applications in node. It favors the typescript language to leverage the power of javascript into new heights. Typescript is a superset of javascript that allows us to use the ES6 (and some of the ES7) spec, today. It also gives us types - we can work in a strongly typed environment. (tedi will only work with a typescript version >= 2.0.0)

Express

express is a great web framework that is already well established in the community and has great support. tedi is not trying to reinvent the wheel here, instead it tries to wrap express's power defining a new approach in terms of architecture using classes, types, and dependency injection as core principles.

Dependency injection

[wikipedia] dependency injection is a software pattern that implements inversion of control for resolving dependencies.

This is a great way to increase modularity and testability right from the start, as tedi forces this pattern to be used. tedi uses inversify.io as the DI engine. It is a great framework that is actively maintained and I'll be glad to incorporate new functionalities that may arise with new releases.

$ mkdir tedi-project
$ cd tedi-project

tsconfig.json (put it in the project root folder)

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "moduleResolution": "node",
        "noImplicitAny": false,
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true
    },
    "exclude": [
        "node_modules"
    ]
}

Compile

You can now compile your .ts files.

$ node_modules/.bin/tsc

Or you can define a npm script.

package.json

"scripts": {
  "compile": "node_modules/.bin/tsc"
},

Use the command to compile.

$ npm run compile
