Development

Emulsify-cli is developed using TypeScript. You can find all of the source files in the src directory, which is organized in the following manner:

• src/index.ts - uses Commander to compose the CLI.
• src/handlers - contains all functions that handle CLI commands, such as emulsify init.
• src/lib - general definitions and logging tools.
• src/schemas - contains JSON-Schema files that describe project, system, and variant configuration. These schema files are used to generate TypeScript types.
• src/scripts - holds utility scripts for the project.
• src/types - type modules live here, auto-generated ones are prefixed with an underscore (_).
• src/util - contains utility functions that are used in handlers to do various things, such as caching systems.

Scripts

• npm run build: builds the project based on the configuration in tsconfig.dist.json.
• npm run build-schema-types: Compiles the json-schema definitions within this project into ts types.
• npm run watch: watches the codebase, and re-compiles every time a change is made.
• npm run format: uses prettier to format all ts files within the codebase.
• npm run lint: uses eslint to lint the codebase.
• npm run test: runs Jest on the codebase. You can specify a path to a single test, and add any flags supported by Jest's CLI.
• npm run type: uses typescript to check all type signatures.
• npm run twatch: runs Jest without coverage, in verbose and watch mode. This is useful for running a single test during active development.
