Roku Builder (Node)

A node package to process a .roku_builder_rebrand.json file.

Usage

Install package:

npm install -D roku-builder

Create .roku_builder_rebrand.json file:

{
    "targets": ["components", "images", "source", "manifest"],
    "channel_config_sections": [],
    "resolutions": ["fhd"],
    "brands": {
        "core": {
            "replacements": {
                "##COPYRIGHT HEADER##": "*****  *****"
            },
            "manifest": {
                "title": "Roku App Name",
                "major_version": 1,
                "minor_version": 0,
                "build_version": "00001",
                "mm_icon_focus_fhd": "pkg:/images/channel-poster_fhd.jpg",
                "mm_icon_focus_hd": "pkg:/images/channel-poster_hd.jpg",
                "mm_icon_focus_sd": "pkg:/images/channel-poster_sd.jpg",
                "splash_screen_fhd": "pkg:/images/splash-screen_fhd.jpg",
                "splash_screen_hd": "pkg:/images/splash-screen_hd.jpg",
                "splash_screen_sd": "pkg:/images/splash-screen_sd.jpg",
                "uri_resolution_autosub": "$$RES$$,SD,720p,1080p",
                "ui_resolutions": "fhd",
                "environment": "production",
                "bs_libs_required": "roku_ads_lib,googleima3",
                "sg_component_libs_required": "Roku_Analytics",
                "supports_input_launch": 1,
                "confirm_partner_button": 1,
                "bs_const": {}
            }
        }
    }
}

Create script using roku-builder, eg: ./scripts/compileBrand.mjs:

import * as builder from "roku-builder";

async function main(brand) {
    console.log(`Processing ${brand}`);
    await builder.doBuild({
        source: "./",
        target: "./dist",
        brand: brand,
        logLevel: "info",
    });
}

await main(process.argv[2]);

Run script to build:

node ./scripts/compileBrand.mjs core

This will build the final output for the app in ./brands/core into ./dist:

Processing core
[RokuBuilder] Config loaded ./
[RokuBuilder] Brand core requested
[RokuBuilder] Processing Brand "core" ...
[RokuBuilder] Process Brand "core" completed
[RokuBuilder] Finalizing Build...
[RokuBuilder] Build complete
