ItentialPromisify

ItentialPromisify wraps cog and adapter functions to enable using async/await with them.

You can also use ItentialPromisify to promisify a single function that expects a callback with arguments in the order results, error.

Installation

npm install --save @itentialopensource/itentialpromisify

Usage with cogs/adapters

Require ItentialPromisfy.

const itentialPromisify = require('@itentialopensource/itentialPromisify');

Wrap an adapter or cog.

const workFlowEngineWrapper = itentialPromisify(cogs.WorkFlowEngine);

Use async/await with any method from the cog you wrapped.

  try {
    const workflowName = 'routerUpgrade';
    const options = {
      variables: {
        new_version: '1.8.8'
      }
    };
    // N.b. no need to pass a callback to the wrapper!
    const saveData = await workFlowEngineWrapper.startJobWithOptions(workflowName, options);
    console.log(JSON.stringify(saveData, null, 2));
  } catch (error) {
    console.log(error.stack);
  }

Usage with single functions

Require ItentialPromisfy.

const itentialPromisify = require('@itentialopensource/itentialPromisify');

Call itentialPromisify on the function

const startJobWithOptionsPromisified = itentialPromisify(cogs.WorkFlowEngine.startJobWithOptions);

Use async/await with the promisified method.

    try {
      const workflowName = 'routerUpgrade';
      const options = {
        variables: {
          new_version: '1.8.8'
        }
      };
      const saveData = await startJobWithOptionsPromisified(workflowName, options);
      console.log(JSON.stringify(saveData, null, 2));
    } catch (error) {
      console.log(error.stack);
    }
