Sending a GET Request with axios:
await this.client.get('/endpoint', { params: { query: ['max', 'kevin'] } })
Results in a URL looking like this
Request GET /endpoint?query[]=max&query[]=kevin
How can I parse this to a string array?
Bonus points if someone knows how to check it in express-validator for format!
You can turn the array to string with to toString:
await this.client.get("/endpoint", {
params: { query: ["max", "kevin"].toString() },
});
This will change the URL to:
/endpoint?query=max,kevin
Then in the express-validator you can validate the array items with wildcard:
req.check('query.*').isLength({ max: 30 })
