Override a route

Overriding a route allows you to change or completely replace a Forest Admin's route behavior.
Changing Forest Admin's behavior
To achieve this, use existing snippets of default routes and modify them according to your needs.
Here are a few examples:
Use extended search by default 
/routes/companies.js
const express = require('express');
const { PermissionMiddlewareCreator, RecordsGetter, RecordsCounter } = require('forest-express-sequelize');
const { companies } = require('../models');
​
const router = express.Router();
const permissionMiddlewareCreator = new PermissionMiddlewareCreator('companies');
​
//...
​
// Get a list of Companies - Check out our documentation for more details: https://docs.forestadmin.com/documentation/reference-guide/routes/default-routes#get-a-list-of-records
router.get('/companies', permissionMiddlewareCreator.list(), (request, response, next) => {
  const recordsGetter = new RecordsGetter(companies);
​
  const params = request.query;
  params.searchExtended = '1';
​
  recordsGetter.getAll(params)
    .then(records => recordsGetter.serialize(records))
    .then(recordsSerialized => response.send(recordsSerialized))
    .catch(next);
});
​
// Get a number of Companies - Check out our documentation for more details: https://docs.forestadmin.com/documentation/reference-guide/routes/default-routes#get-a-list-of-records
router.get('/companies/count', permissionMiddlewareCreator.list(), (request, response, next) => {
  const recordsCounter = new RecordsCounter(companies);
​
  const params = request.query;
  params.searchExtended = '1';
​
  recordsCounter.count(params)
    .then(count => response.send({ count }))
    .catch(next);
});
​
//...
With this snippet, only the companies collection would use extended search by default.
Using extended search is less performant than default search. Use this wisely.
Protect a specific record
/routes/companies.js
router.delete('/companies/:recordId', permissionMiddlewareCreator.delete(), (request, response, next) => {
  if (request.params.recordId === 82) {
    response.status(403).send('This record is protected, you cannot remove it.');
    return;
  }
​
  const recordRemover = new RecordRemover(companies);
  recordRemover.remove(request.params.recordId)
    .then(() => response.status(204).send())
    .catch(next);
});
Replacing Forest Admin's behavior
To achieve this, simply remove the next() statement of any route:
/routes/companies.js
...
​
// Create a Action Approval - Check out our documentation for more details: https://docs.forestadmin.com/documentation/reference-guide/routes/default-routes#create-a-record
router.post('/companies', permissionMiddlewareCreator.create(), (req, res, next) => {
  // >> Add your own logic here <<
});
​
...
For instance, if you have a Users collection, you might want to create your users via your own api:
/routes/users.js
...
​
const axios = require('axios');
const { users } = require('../models');
​
...
​
router.post('/users', permissionMiddlewareCreator.create(), (request, response, next) => {
  const recordCreator = new RecordCreator(users);
  const data = request.body.data.attributes;
  axios({
    url: 'https://<your-api>/users',
    method: 'post',
    data: data,
  })
    .then(async (result) => {
      response.send(await recordCreator.serialize(result.data));
    })
    .catch((error) => {
      console.log('error:', error);
    });
});
