API Charts

This is the official documentation of the @forestadmin/agent Node.js agent.

API charts in the legacy agents were declared using express routes.

In the new agent, you will need to use either the agent.addChart or the collection.addChart function, depending on if the chart is to be displayed on a record of a collection or a dashboard.

You can find the full documentation of chart customization here.

How to migrate

Migrating should be straightforward: the only differences are that:

  • dashboard charts are now declared using the agent.addChart function.

  • collection charts are now declared using the collection.addChart function, and access the record id using context.recordId instead of request.query?.record_id.

  • Both types should use the resultBuilder helper to return the chart data.

router.post('/stats/mrr', (req, res) => {
  // Load data
  const from = moment.utc('2018-03-01').unix();
  const to = moment.utc('2018-03-31').unix();
  const charges = await stripe.charges.list({ created: { gte: from, lte: to } });

  // Compute chart
  const mrr = charges.reduce((acc, charge) => acc + charge.amount, 0);
  const json = new Liana.StatSerializer({value: mrr}).perform();
