processto

Processto uses globby to process directories of markdown and yaml files to a mirrored tree of JSON files. Additionally, with the convertMode: "source" option you can convert back from json to the input markdown and yaml files. This is mostly useful for blogs or static content for websites or other places where json is used but the readability of yaml is useful.

Getting Started

Install with npm

npm install --save-dev processto

Usage

You can then use the cli

processto "content/**/*.{yml,md}" --outputDir output

And watch files to automatically recompile them.

processto "content/**/*.{yml,md}" --outputDir output --watch

With an input markdown file such as this:

---
test: frontmatter
draft: true
num: 1
---

# processto

Process a directory of markdown *and* yaml files to JSON files

This would be the resulting JSON:

{
  "test":"frontmatter",
  "draft":true,
  "num":1,
  "bodyContent":"# processto\r\n\r\nProcess a directory of markdown *and* yaml files to JSON files",
  "bodyHtml":"<h1 id=\"processto\">processto</h1>\n<p>Process a directory of markdown <em>and</em> yaml files to JSON files</p>\n",
  "title":"processto",
  "dir":"test/data/output",
  "base":"frontmatter.json",
  "ext":".json",
  "sourceBase":"frontmatter.md",
  "sourceExt":".md"
}

And given the following input directory:

.
├── L1
│   ├── L2
│   │   └── test2.yml
│   └── test.yml
├── README.md
└── frontmatter.md

It would produce this directory output:

.
├── L1
│   ├── L2
│   │   └── test2.json
│   └── test.json
├── README.json
└── frontmatter.json

Advanced Usage

Processto will also output some summary data as a json object to stdout when used with the --stdout option. Then you can direct that to a file.

processto \"content/**/*.{yml,md}\" --stdout --outputDir output > summary.json

summary.json will contain:

{
  "fileMap":{
    "test/data/output/frontmatter.json":"{...}",
    "test/data/output/L1/test.json":"{...}",
    ...
  }
  "sourceFileArray":[
    "test/data/input/frontmatter.md",
    "test/data/input/L1/test.yml",
    ...
  }

Options

module.exports = {
  // The directory output will be processed to.
  outputDir: './dist',
  // Watch mode, recompile on file changes.
  watch: false,
  // Prefix for output filenames, default is no prefix, just the original filename.
  filenamePrefix: '',
  // For markdown files how many characters should be included in an add `preview` property. 0 for no preview.
  preview: 0,
  // Include the markdown document title as `title` on the resulting json objects.
  includeTitle: true,
  // Include the directory as `dir` on the resulting json objects.
  includeDir: true,
  // Include the filename (.json) as `base` on the resulting json objects.
  includeBase: true,
  // Include the extension (.json) as `ext` on the resulting json objects.
  includeExt: true,
  // Include the source filename (.md / .yml) as `sourceBase` on the resulting json objects.
  includeSourceBase: true,
  // Include the source extension (.md / .yml) as `sourceExt` on the resulting json objects.
  includeSourceExt: true,
  // Convert mode. Possible options for this are 'json' or 'source'.
  convertMode: 'json',
  // Whether to output to stdout or not.
  stdout: false,
  // Custom markdown renderer function, null to use the default: `marked`.
  markdownRenderer: null,
}

Enjoy!
