Using remult in express routes ​

When using BackendMethods, remult is automatically available. Still, there are many use cases where you may want to create your own express endpoints without using BackendMethods but would still want to take advantage of Remult as an ORM and use it to check for user validity, etc...

If you tried to use the remult object, you may have got the error:

Error: remult object was requested outside of a valid context, try running it within initApi or a remult request cycle

To get remult, simply use the api.withRemult middleware - that will initiate the remult object for you with the relevant request information

Here's an example of how to do that:

const app = express();
...
const api = remultExpress({
    entities:[Task]
})
app.post('/api/customSetAll', api.withRemult, async (req, res) => {
    if (!remult.authenticated()) {
        res.sendStatus(403);
        return;
    }
    if (!remult.isAllowed("admin")) {
        res.sendStatus(403);
        return;
    }
    const taskRepo = remult.repo(Task);
    for (const task of await taskRepo.find()) {
        task.completed = req.body.completed;
        await taskRepo.save(task);
    }
    res.send();
});
