Expressjs and Body-parser Posting Articles
If you mean, how to refactor your code in a better way, I would suggest these:
1-) use destructuring to parse req.body like this:
app.post("/article/add", function(req, res) { const { title, author, body } = req.body; let article = new Article({ title, author, body }); article.save(function(err) { if (err) { console.log(err); return; } else { res.redirect("/"); } });});2-) use async await syntax:
app.post("/article/add", async function(req, res) { const { title, author, body } = req.body; let article = new Article({ title, author, body }); try { article = await article.save(); res.redirect("/"); } catch (err) { console.log(err); return; }});
