@ldo/cli

The @ldo/cli is a command line interface for initializing LDO and building ShapeTypes.

Setup

Automatic Setup

To setup LDO, cd into your typescript project and run npx @ldo/cli init.

cd my-typescript-project
npx @ldo/cli init

Install the LDO dependencies.

npm install @ldo/ldo
npm install @ldo/cli --save-dev

Create a folder to store your ShEx shapes:

mkdir shapes

Create a script to build ShEx shapes and convert them into Linked Data Objects. You can put this script in package.json

{
  ...
  scripts: {
    ...
    "build:ldo": "ldo build --input ./shapes --output ./ldo"
    ...
  }
  ...
}

Generating a ShapeType

@ldo/cli generates shape types using the *.shex files in the "input" folder. If you followed the instructions above, run the following command:

npm run build:ldo

This will generate five files:

• ./ldo/foafProfile.shapeTypes.ts <-- This is the important file
• ./ldo/foafProfile.typings.ts
• ./ldo/foafProfile.schema.ts
• ./ldo/foafProfile.context.ts

Creating a new project to distribure shapes

Sometimes, you might want to distribute shapes to others. The easiest way to do that is to deploy them to NPM. The LDO CLI has an easy-to-use command for generating a standalone project just for your shapes.

npx @ldo/cli create ./my-project

This script will generate a project with a place to put your shapes. Running npm publish will build the shapes and push to project to NPM for you.
