Tracking query

Tracking query is very popular case. Argon router gives you instrument with name query tracker, which allows you to watch query & controls it without headache.

Allowed parameters types: number, string, boolean, array, string literal, any

Basic example (persistent dialog)

// settings/model/root.ts

import { router } from '@shared/router';
import { createDialog } from '...';

const dialog = createDialog();
const tracker = router.trackQuery({
  dialog: 'age',
});

sample({
  clock: tracker.entered,
  target: dialog.open,
});

sample({
  clock: tracker.exited,
  target: dialog.close,
});

sample({
  clock: dialog.closed,
  target: tracker.exit,
});

Edit team member (in persistent dialog)

// team/model/root.ts

import { parameters } from '@argon-router/core';
import { router } from '@shared/router';
import { createDialog } from '...';

const dialog = createDialog();
const tracker = router.trackQuery({
  dialog: 'team-member',
  id: parameters.number,
});

// triggered for:
// /team?dialog=team-member&id=1
// /team?dialog=team-member&id=10000

// not triggered for:
// /team?dialog=team&id=1
// /team?id=10000
// /team?dialog=team&id=not_number

Exit without loss parameters

sample({
  clock: someEvent,
  // do not erase 'uid' parameter when exit
  fn: () => ({ ignoreParams: ['uid'] }),
  target: tracker.exit,
});
