contexter-cli

A demo application that extends the npm contexter metadata extraction capability to images also

This is a complete application to show the core contexter library capabilities

Reactively extract all available data from files (including images) in a directory to one javascript object

contexter-cli has two commands, serve and write. Both accept a directory path

• serve shows the context object generated in a browser window
• write writes the context object generated to a file or console

Usage

Sample dir structure

dir/
|-- assets/
|   |-- photo.jpg   <--- metadata like 'colors'
|   |-- style.css
|   `-- posts.yml
|
|-- index.html
|-- README.md
`-- notes.txt

CLI

contexter-cli serve .

terminal output

Started contexting dir...
  /assets/photo.jpg added
  /assets/posts.yml added
.done!
The server now is running at http://localhost:3000

[BS] Access URLs:
 -------------------------------------
          UI: http://localhost:3001
 -------------------------------------
 UI External: http://192.168.15.6:3001
 -------------------------------------
[BS] Watching files...

Open browser to http://localhost:3000

You will see the directory structure and a dynamic context JavaScript object that mirrors it

The result is a reactive context variable equivalent to:

var context = {
              dir: {
                    assets: {
                          "photo.jpg": {
                                  colors: [
                                        "#bbbbbb",
                                        "#080808",
                                        "#5c5c5c",
                                        "#787878",
                                        "#646464"
                                        ], ...
                            },
                          "posts.yml": {...}
                    },
              datafiles: [
                    {...}   // posts.yml
                    ],
              images: [
                    {...}   // photo.jpg
                    ],
              unknowns: [
                    ]       // empty
            }

Getting started

1.- Install with npm:

npm install contexter-cli --global

2.- Then run the command serve with a path to the directory

contexter-cli serve <path-to-dir>

3.- Wait for the following output

...
.done!
The server now is running at http://localhost:3000

[BS] Watching files...

4.- In a browser open http://localhost:3000

5.- Play with the dynamic context JavaScript object

...it is reactive, you can update files while the App is running to see the changes in the browser live!
