Append a query param to a GET request?

After looking at Axios' README, it looks like the second argument needs the key params. You can try:

app.get('/api/posts', async (req, res, next) => {    try {        const url = 'https://myurl.com/blah/blah';        const options = {            params: { tag: req.query.tag }        };        const response = await axios.get(url, options);        res.json(response.data);    } catch (err) {        // Be sure to call next() if you aren't handling the error.        next(err);    }});

If the above method does not work, you can look into query-string.

const querystring = require('query-string');app.get('/api/posts', async (req, res, next) => {    try {        const url = 'https://myurl.com/blah/blah?' +            querystring.stringify({ tag: req.params.tag });        const response = await axios.get(url);        res.json(response.data);    } catch (err) {        next(err);    }});

Responding to your comment, yes, you can combine multiple Axios responses. For example, if I am expecting an object literal to be my response.data, I can do:

const response1 = await axios.get(url1)const response2 = await axios.get(url2)const response3 = await axios.get(url3)const combined = [    { ...response1.data },    { ...response2.data },    { ...response3.data }]
