SurrealHTTP() class

[nxfi777]

Not sure how useful this will be but I found myself needing to use my database over HTTP in serverless cloud functions. Using Websockets there would have several issues do to their short-lived nature (performance overheads, resource usage, connection disruptions, etc...). I noticed that the python sdk contains this class, which is great, but I think this also needs it. Bare in mind I have never used rust.

class SurrealHTTP {
    constructor(url, ns, db, auth) {
        this.url = url;
        this.ns = ns;
        this.db = db;
        this.auth = auth;
    }

    async query(sql, bindings) {
        let config = {
            headers: {
                'NS': this.ns,
                'DB': this.db,
                'Accept': 'application/json'
            },
            params: bindings   // bind variables in the request params
        };

        // auth configuration based on whether JWT token or user and password are used
        if (this.auth.token) {
            config.headers['Token'] = `${this.auth.token}`;
        } else {
            // Basic authentication
            config.auth = {
                username: this.auth.username,
                password: this.auth.password
            };
        }

        try {
            const response = await axios.post(`${this.url}/sql`, sql, config);
            if (response.data[0].status !== 'OK') {
                throw new Error('Server responded with a status other than OK.');
            }

            return response.data;
        }
        catch (error) {
            console.error(error);
            return null;
        }
    }
}

EDIT: Added JWT auth
