Library Usage

Alternatively the package modules may be imported and applied within a Typescript project:

import * as cli from '@elaraai/cli'
// create a simple application to create a project, add a datasource, build and deploy
const project_dir = 'path_to_workspace'
async function run() {
     // create a project
     let project_config = await cli.init({ 
         name: 'A project', 
         dir: project_dir 
     })
 
     // add a deployment
     project_config = cli.addDeployment({
         dir: project_dir,
         server: 'https://server_url',
         name: 'test',
         config: project_config
     })
 
     // add a datasource to the project
     project_config = cli.addRangeDataSource({
         name: "Datasource",
         dir: project_dir,
         def_dir: 'src/sources',
         config: project_config,
         start: 1.5,
         stop: 1000,
         step: 2.3
     });
 
     // build the schema
     let build = cli.buildSchema({ 
         dir: project_dir, 
         config: project_config 
     });
     if(build === false) {
         //...
     }
 
     // deploy the schema
     let deploy = await cli.deploySchema({ 
         dir: project_dir, 
         config: project_config, 
         deployment: 'test' 
     });
     if(deploy === false) {
         //...
     }
}
 
run()
