Combining a variable with a non-string element in ExpressJS

I am currently working on a project using the MEAN stack, and I have a task that requires executing a query in MongoDB. The query is as follows: db.locations.find({"name":/sometext/}); This query will return all results where it finds "sometext" in the name field.

Here is an example of my Express code:

app.post('/api/request/test1', function(req, res) {
    res.contentType('application/json');
    console.log(req.body.name);
    var a = req.body.name;
    var x = /+a+/;
    
    locations.find({"name":x}).toArray(function (err, items){
        res.send(items);
    })    
})

However, the code above is not functioning correctly as it gives an error with var x = /+a+/.

The desired end result is to have something like this: Let's say the variable a="TEST", so x should be /TEST/ without any single or double quotes, otherwise MongoDB won't recognize it.

Thank you.

Answer №1

Shout out to @Pointy for helping me find the solution.

I crafted a fresh regular expression using the following code:

var x = new RegExp(req.body.name);

Now, when req.body.name is set to TEST, x will store /TEST/ as its value.

Much appreciated!
