# PLC Bundle V1 TypeScript Reference Implementation
2
+
3
+
This script is a compact, readable reference implementation for creating PLC Bundle v1 archives. It fetches operations from the PLC directory and generates a complete, verifiable repository of data bundles.
4
+
5
+
It is fully compliant with the [PLC Bundle v1 Specification](https://github.com/atscan/plcbundle/blob/main/SPECIFICATION.md).
6
+
7
+
## Features
8
+
9
+
- **Spec Compliant:** Correctly implements hashing, chaining, serialization, and boundary de-duplication.
10
+
- **Reproducible:** Generates byte-for-byte identical bundles to the official Go implementation.
11
+
- **Efficient:** Uses a memory-efficient method to handle duplicates between bundle boundaries.
12
+
- **Standalone:** Single-file script with clear dependencies.
13
+
14
+
## Usage
15
+
16
+
This script can be run with **Bun (recommended)**, Deno, or Node.js.
17
+
18
+
The script accepts one optional argument: the path to the output directory where bundles will be stored. If omitted, it defaults to `./plc_bundles`.
19
+
20
+
### Bun (Recommended)
21
+
22
+
Bun is the fastest and easiest way to run this script, as it handles TypeScript and dependencies automatically.
23
+
24
+
```sh
25
+
# Install dependencies
26
+
bun install
27
+
28
+
# Run the script to create bundles in ./my_plc_bundles
29
+
bun run plcbundle.ts ./my_plc_bundles
30
+
```
31
+
32
+
### Deno
33
+
34
+
Deno can also run the script directly. You will need to provide permissions for network access and file system I/O.
35
+
36
+
```sh
37
+
# Run the script with Deno
38
+
deno run --allow-net --allow-read --allow-write plcbundle.ts ./my_plc_bundles
39
+
```
40
+
41
+
### Node.js (with TypeScript)
42
+
43
+
If using Node.js, you must first install dependencies and compile the TypeScript file to JavaScript.
44
+
45
+
```sh
46
+
# Install dependencies
47
+
npm install
48
+
49
+
# Compile the script
50
+
npx tsc
51
+
52
+
# Run the compiled JavaScript
53
+
node dist/plcbundle.js ./my_plc_bundles
54
+
```
