This is a template for creating a Node https application that hosts an Aurelia SPA using Koa as a router and Mongo as a database written in Typescript.

1. Install Node

Requires at least node version 7 2. Download Mongo 3. Install Mongo

Of course you do not need to install Mongo locally. You can connect to any other MongoDB you have.
Make sure to update the Mongo connection string in config/default.json

Run the following commands from the command line

4. npm install gulp -g
5. npm install jspm -g
6. npm install typings -g

Ensure you are in mkaunts/ i.e. the folder with the package.json

7. npm install
8. jspm install
9. typings install

We use gulp as a taskrunner to handle building the app.
All of the gulp tasks are located in the build/ folder.

This task transpiles the source Typescript located in src/ into Javascript and places it in the app/ folder.

This task essentially runs a gulp build whenever it detects changes to the source code.

This task bundles the client source.
The build/bundles.js file determines what is bundled and where. This file will need to be updated if you add more jspm packages.

This tasks produces a folder called export/ that contains the bundled client code and any other files that are necessary for the client but cannot be placed in the bundle.
The idea here is that you want to publish the smallest amount of code possible. For example 'jspm_packages/system.js' is included in the export since it is necessary to load packages from the bundle so it cannot be a part of the bundle. Also it can be important to export some css files that are needed in the index.html.
The build/export.js file determines what is exported.

node ./dist/node/app.js

Will start the app from the root folder i.e. mkaunts/
Alternatively just hit F5 in VS Code.

Source maps are generated when we build that allow us to debug the Typescript directly instead of the Javascript.
Debugging the server code in VS Code works.
Debugging the client coe in Chrome works. However, the client sourcemaps have an inline copy of the Typescript. This is because the src folder is not being served by our app so Chrome Chrome is not able to find the true source Typescript.

The server and client portions of the application import packages in different ways.
They are both written in Typescript though. So be sure to download type defintion files for any packages you are using.

The client uses npm to manage packages. These packages are in the node_modules/ folder.

npm install <package_name> --save 

will install a package

The client uses jspm to manage packages.
Jspm can install packages from npm and Github.

jspm install <package_name>

will install a package.

Jspm will automatically update the app/public/config.js whenever you add a package. This is a map between normalized package names and their paths.

When installing a package on the client be sure to add it to the build/bundles.js file if you intend on bundling.

We Mocha as a test framework, Chai as an assertion library, Sinon as a stubbing/mocking library, and Karma as a client side test runner.

mocha

will start the Node tests.

note: using Typescript version greater than 2.2 will break karma unit tests. Hoping to find the solution to this soon.

karma start

will start the Aurelia tests.

Type definition files allow us to define type information for Javascript code.

This is important when importing third party packages since they are most likely Javascript libraries that do not contain type information.

Type defintion files have the extension d.ts and are usually written by someone else who did not actually write the library they are defining types for.

Typings is similar to jspm or npm except that it is just for installing type definition files.

The

typings install

step earlier downloaded type defintion files into the typings/ folder.

Typings can install a type definition file with

typings install <package_name> --save

We can also install type definition files with npm.

npm install @types/<package_name> --save-dev

will install a type definition file into the node_modules/@types/ folder.

It seems like @types is the main way that type definition files will be acquired in the future.
