Pieceup is a small library designed for Node, with functional programming in mind, that aids in the process of setting up a static site generator. In a more specific sense, it provides a structure and a guideline for modifying source code in a procedural manner. (Since that's what static site generators mostly do anyways)
npm install pieceup-js
Pieceup implements a scheme comprised of two structures: sourceObject, an object that contains the source code, data and other relevant information, and a sourceTree, an array that contains all the sourceObjects pertinent to a process. Then, these objects are modified using a "pipeline", an adaptation of a pipe function tailored for this particular use.
A Source Tree can be created using createSourceTree(), which will read the contents of a folder and generate the array.
Alternatively, a single file (which would result in a Source Object) can be read by using setFileSourceObj().
Pipelines can be created by using setPipeline(). This provides a way of applying several functions, one after another, to each object in a Source Tree. A more detailed explanation is provided in the documentation.
// Include the library
const pieceup = require('pieceup-js')
// Store the source tree in a variable
// Read and get the source tree for those blog entries
const entriesSource = pieceup.createSourceTree(blogPath, {
patternArray: [
'/**/*.md', // Select all .md files,
'!/**/_*' // Exclude files starting with '_'
]
})
// Set up a pipeline to do modifications to the tree
const blogEntryPipeline = pieceup.setPipeline(
insertFrontMatter,
renderMarkdown,
nestInLayout)
// Execute the pipeline on the tree and store the result
// Note that the argument provided is a Source Tree, but the setPipeline() function will iterate over it and call the composition of functions using each Source Object as the argument.
var renderedBlog = blogEntryPipeline(entriesSource)
// Write to a file. The supplied function will provide the filename to use
pieceup.toFile(renderedBlog, function (obj) {
return obj.name + '.html'
