DBPF.js a performant dbpf file reader written in TypeScript

This is a performant library for reading DBPF files in TypeScript/JavaScript. Currently, it only parses the header, index and index entries, but a plugin system is planned to allow for reading and handling of the actual data.

Playground/Interactive Testing (github.io)

To see the library in action, you can visit the playground.

You can also build and run the playground locally by following the instructions in Building and Interactive Testing:

Usage

This library is available on npm:

• for interactive testing (playground), skip to Building and Interactive Testing

npm install dbpf.js

import { DBPF } from 'dbpf';

let file: string;
// Node.js:
file = 'path/to/file.package';
// Browser:
file = input.files[0]; // where input is an <input type="file"> element

let dbpf = await DBPF.create( file );

For more advanced usage, see the API documentation.

• For all exported members, see: the UMD export.

Building and Interactive Testing

Building and testing is pretty simple. The following commands will clone the repository, install dependencies, build the library, and launch a test environment (playground) in the browser. This test environment is identical to the one hosted on github.io, just hosted locally.

• NOTE: make sure you have familiarized yourself with what is in package.json and the scripts directory before running npm run commands!

git clone https://github.com/anonhostpi/DBPF.js
cd DBPF.js

# Install dependencies
npm run devinstall # wraps `npm install`

# !!! TO ADD DEPS, PLEASE USE: !!!
# npm run devinstall/devuninstall -- <npm-install-args>
# ex: npm run devinstall -- @microsoft/tsdoc --save-dev
# this helps with maintaining package.json's format

# Build the library
npm run build

# Launch test environment
npm run test
# - sets up a local static server at http://localhost:8080 and opens a browser to a test page for interactive testing

Both the build and test build will use webpack to bundle the library for the browser.

Entry Points

The entry points are as follows:

• Built files:
  • dist/DBPF.js - The library for use in node.js
  • dist/DBPF.web.js - The library for use in the browser
  • test/serve/index.html and test/serve/test.web.js - The test environment for the browser
    • a copy of DBPF.web.js is also copied to test/serve and is automatically loaded by the test environment
• Source files:
  • src/DBPF.ts - The main library
  • src/test.web.ts - The script used by the interactive test environment

Building the Docs Locally

To get the full set of docs locally, run either:

• npm run docs: to build the typedoc documentation (./wiki)
• npm run test:pub: to build the typedoc documentation and run docusaurus:serve (view the docs from your browser).
  • also runs some minor cleanup work before building with docusaurus

The full set of docs does not need to be built locally to be used or read.

• The typedocs are sourced from the comments in the ./src files
• The project docs are sourced from ./docs.

There are no other documentation sources in this repo other than this README and the LICENSE.
