</div>


## Installation

```bash
npm install -g @sidekick-coder/db
```

## Usage 

Create db.config.yml

```yaml
name: tasks
provider:
  name: file
  config:
    format: markdown
    path: ./tasks-folder # path to the folder with markdown files
```

```bash
db list --where "status=done" # list 

db find --where "id=01" # find single item

db create --data "title=New task&status=todo&body=This is a new task" # create new item

db update --data "status=done" --where "id=01" # update item

db destroy --where "id=01" # delete item
```

## Providers 

- [File](./docs/providers/file.md)
- [Folder](./docs/providers/folder.md)
- [Notion](./docs/providers/notion.md)
- [Vault](./docs/providers/vault.md)

## Database

A database in the context of this lib refers to any data that can be converted to an array of objects.

Examples can be:

- list of plain text files with key value pairs
- list of markdown file with frontmatter
- list of json files
- list of folders
- list of rows from a SQL Table (Postgres, MySQL, etc)
- etc...

## Config file

The config file is a yaml file that defines the one or more databases definitions.

The cli will always look for a the `db.config.yml` file in the current directory, unless you pass a different path as a flag.

```bash 
db -f "path/to/config.yml"
```

### Single Database config sample

```yaml 
name: tasks
provider:
    name: file
    config:
        path: data
        format: markdown
        id_strategy: increment
view:
    default: default
    sources:
        dirs: views
        files: [./views/default.yml]
        items:
            - name: archived
              where:
                  archived: false
```

### Multiple Databases config sample

```yaml 
databases:
    default: tasks
    sources:
        files: ["content/tasks/db.config.yml"]
        patterns: ["content/*/db.config.yml"]
        items:
            - name: tags
              provider:
                  name: file
                  config:
                      path: ./content/tags/data

            - name: code-snippets
              provider:
                  name: file
                  config:
                      path: content/code-snippets/data
```

You can load the value from a file by adding the extension to the value

```bash
db list --where '{"path": "data"}'

include: [id, title, status]

# exclude properties
exclude: [body]

# sort by
sort-by: id
sort-desc: true

# where statments
where: 
    status: done

render: console # render to use
render_options:
    columns:
        - label: ID
          value: id
          width: 3 # 3% terminal width

        - label: Status
