chunks-tracker

a small library to track chunks the rollup generates

Why?

you could this prevent rollup from creating new files for chunks and filling you build directory

Usage

import chunksTracker from "chunks-tracker";

export default {
  input: "index.js",
  output: {
    // ...
    chunkFileNames: chunksTracker({ ...yourOptions }),
    // if you to prevent rollup from creating new files for chunks and filling you build directory
    chunkFileNames: chunksTracker({
      dir: "<your-build-folder>",
      storeIn: "chunks.json",
      preventRepeat: true,
    }),
  },
};

Options

all options are optional

dir

default: undefined

the path to your build directory relative to the current working directory (cwd)

format

default: undefined

the format for your build files

schema

default: "[name]-[hash].js"

the schema for your chunks names for example: if your schema is the default chunksTracker will replace "[name]" with the file name and replace "[hash]" with random letters and numbers

[name]: the file name [hash]: some random letters and numbers [format]: the format for the file (eg. cjs) you need to pass format

storeIn

default: false

a path to a json file relative to the build folder

the json file will be an object where

the keys are the path of the source files of the chunks relative to cwd
the values are the path of the chunks relative to the build folder

for example:

if dynamically you import a file called (for example) "my-file.js" in cwd the json file will look like this:

{ "my-file.js": "my-file-2a8e18e.js" }

preventRepeat

default: false

need storeIn to be specified

a boolean if true will prevent rollup from creating new files for the same source files

for example:

if you're in watch mode

and you dynamically import a file called "my-file.js"

in the first run chunks-tracker will store it's source file path and it's generated chunks path (as shown in storeIn) and return generated chunks path to rollup

if you then update it

chunks-tracker will read the json file and return generated chunks path to rollup so rollup will update that file instead of creating a new one

hashLen

default: 20

the length of the hash(s) in generated chunks
