# MicroCODE's 'mcode-data' package

A public NPM Package of our internal data processing tools for Frontend and Backend JavaScript NodeJS projects.

This is an extremely 'light weight' package with _zero dependencies_.

Identical data and math handling on both...

-   **Frontend** - in the Browser UI
-   **Backend** - in the Server MVC

## Description

This is our own internal data processing (data) code. It is used to gain more control over JavaScript data types and type coercion. Building large, extensible applications it is inevitable that you will have to carefully control data type coercion and handle type checking in a very common/consistent manner. Both of these can be defined as 'data handling', and this is our library for that in all our apps.

```
> node examples
```

## Dependencies

-   **Production**

1. None

-   **Development**

1. Node.JS - standard runtime environment
2. JSDocs - our preferred JavaScript documentation system
3. Jest.JS - our preferred JavaScript testing framework

## Development

When building a large application its important that the entire team agreed to common data handling practices.

### Installing

-   Get to a terminal session in the local repo folder of your project.
-   Use 'npm install' to load the package. It can be used 'stand-alone'...

```
npm install mcode-data
```

### Testing

This package includes a simple demo module: **examples.js**.
Running it directly will show you a set of examples for using all the data library functions.

-   From your project directory after installation...

```
node .\node_modules\mcode-data\examples
```

...this will deomnstrate thru console logging various uses of the mcode-data functions.

-   To test with **JEST**:
-   From the **mcode-data** package directory...

```
npm install --save-dev jest
npm test
```

## Included Functions

These are the functions we want at the ready in any module for development and debug.

### Documentation

We believe is explicit code documentation, for other users, and for our 'future selves'.<br>
JSDocs is a standardized system for documenting functions and data structures that produces three (3) primary outputs:

1. Inline documentation for the coder.
2. Intellisense popup documentation for the coder for every function.
3. External 'reference manual' documentation for your entire code base, if used consistently.

-   This entire project--like all our projects--is documented with **JSDocs**.

-   To install JSDocs use, get to a terminal session in the project folder...

```
npm install --save-dev jsdoc
```

-   Configure JSDoc processing in...

```
jsdoc.json
```

-   To regenerate the JSDocs from all source code, use the following command (from the project root directory)...

```
jsdoc -c .jsdoc.json
```

...then open ./docs/index.html
