lines-loader

Webpack loader that loads a text file as an array of its lines.

Usage

Add the loader to your Webpack config:

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.lines\.txt$/,
        use: "lines-loader"
      }
    ]
  }
}

Now you can import corresponding files in your entry script:

index.js

import lines from "./example.lines.txt"

console.log(lines.length)

example.lines.txt

maxine
chloe
rachel

Variable lines in index.js will look like this:

["maxine", "chloe", "rachel"]

Advanced Usage

All options can be set inline. Example:

index.js

import lines from "./example.lines.txt?nonEmpty=false"
import linesNormalized from "./example.lines.txt?sort&unique"

console.log(lines.length)
console.log(linesNormalized.length)

example.lines.txt

maxine
chloe

rachel


chloe

Variable lines in index.js will look like this:

["maxine", "chloe", "", "rachel", "", "", "chloe", ""]

Variable linesNormalized in index.js will look like this:

["chloe", "maxine", "rachel"]

Options

Option|Default|Description ---|---|--- trim|true|If true, extracted lines' left and right whitespace will be trimmed. nonEmpty|true|If true, empty lines will be skipped. If option trim is true, any lines that only contain whitespace will be also skipped. sort|false|If true, extracted lines will be sorted alphabetically. unique|false|If true, there will not be any duplicates in extracted lines. randomPick|false|If true, the exported value will be a function instead of a string[]. That function does not take any arguments an returns a random pick from the extracted lines.
