A library and command-line tool for rendering Mapeo configuration files
npm install mapeo-config-renderer

Mapeo Config Renderer is a command line application that provides a visual interface for Mapeo configuration files from a local folder. It allows you to view the presets and icons defined in the Mapeo configuration project.
- Visual interface for Mapeo configuration files
- Displays presets and icons
- Reloads on config change
You can run Mapeo Config Renderer using npx or npm. Inside a Mapeo configuration folder run:
```
npx mapeo-config-renderer
Or to install Mapeo Config Renderer globally, use the following command:
``
npm i -g mapeo-config-renderer
Open your browser on http://localhost:5000.
You can also pass an argument with the path to your Mapeo configuration folder, eg.: npx mapeo-config-renderer /path/to/my-config
You can also use Mapeo Config Renderer as a library in your Node.js projects. It supports both legacy Mapeo and new CoMapeo formats.
`javascript
// Import the entire library
const mapeoConfigRenderer = require("mapeo-config-renderer");
// Or import specific functions
const {
getPresets,
getFields,
getIcon,
getMessages,
getDefaults,
getMetadata,
getStylesheet,
getConfig,
} = require("mapeo-config-renderer");
// Example: Parse the entire configuration
const configDir = "/path/to/mapeo-config";
getConfig(configDir)
.then((config) => {
console.log("Configuration loaded:", {
presets: config.presets.length,
fields: config.fields.length,
messages: Object.keys(config.messages).length,
format: config._format, // 'legacy' or 'comapeo'
});
})
.catch((err) => {
console.error("Error loading configuration:", err);
});
// Example: Get presets from a configuration folder
const presetsDir = "/path/to/config/presets";
getPresets(presetsDir)
.then((presets) => {
console.log("Found presets:", presets.length);
})
.catch((err) => {
console.error("Error loading presets:", err);
});
// Example: Get fields from a configuration folder
const fieldsDir = "/path/to/config/fields";
getFields(fieldsDir)
.then((fields) => {
console.log("Found fields:", fields.length);
})
.catch((err) => {
console.error("Error loading fields:", err);
});
// Example: Get an icon
const iconPath = "/path/to/config/icons/my-icon-100px.svg";
getIcon(iconPath)
.then((iconData) => {
console.log("Icon data loaded:", iconData.length);
})
.catch((err) => {
console.error("Error loading icon:", err);
});
// Example: Get translation messages
const messagesDir = "/path/to/config/messages";
getMessages(messagesDir)
.then((messages) => {
console.log("Found translations for languages:", Object.keys(messages));
})
.catch((err) => {
console.error("Error loading messages:", err);
});
// Example: Get defaults.json
getDefaults("/path/to/config")
.then((defaults) => {
console.log("Default settings:", defaults);
})
.catch((err) => {
console.error("Error loading defaults:", err);
});
// Example: Get metadata.json
getMetadata("/path/to/config")
.then((metadata) => {
console.log("Configuration metadata:", metadata);
})
.catch((err) => {
console.error("Error loading metadata:", err);
});
// Example: Get style.css
getStylesheet("/path/to/config")
.then((css) => {
console.log("Custom stylesheet loaded:", css.length, "bytes");
})
.catch((err) => {
console.error("Error loading stylesheet:", err);
});

In the project directory, you can run:
- npm start: Runs the app in the development mode. Open http://localhost:5000 and http://localhost:3000 to view it in your browser. Api doesn't auto reload.npm run build
- : Builds the app for production to the build folder.npm run dev
- : Starts both api server and React app in dev modenpm test
- : Runs the React app testsnpm run test:api
- : Runs the API library testsnpm run test:all
- : Runs all testsnpm run lint
- : Formats code using Prettiernpm run lint:check
- : Checks code formatting without making changesnpm run generate:fixtures
- : Generates test fixtures for both legacy Mapeo and CoMapeo formatsnpm run test:fixtures
- : Generates fixtures and tests the library with them
The project includes scripts to generate test fixtures for both legacy Mapeo and CoMapeo formats. These fixtures can be used to test the library with realistic data.
- Legacy Mapeo Fixture: A complete legacy Mapeo configuration with presets, fields, and icons.
- CoMapeo Fixture: A complete CoMapeo configuration with presets, fields, messages, icons, defaults.json, metadata.json, and style.css.
To generate the fixtures, run:
``
npm run generate:fixtures
To test the library with the fixtures, run:
```
npm run test:fixtures
This project uses Husky and lint-staged to run linting on staged files before committing. This ensures that all committed code follows the project's formatting standards.
The project has two GitHub Actions workflows:
1. Tests: Runs on every push to main and on pull requests. It runs linting checks and all tests.
2. Publish to NPM: Automatically publishes the package to NPM when changes are pushed to the main branch.
