I'm currently tweaking a system, so during the process, I wanted to implement real-time information search, so the following code was:

<%= results7.filter(i => i.nick === req.autor) %>

A note of the code above, which in console.log looks like this: console . Until then, everything is ok, he is actually pulling the information as requested, an observation is that the req.autor came from <%infoReq.forEach(req => {%> And all of this is collected by index.js through res.render('./requerimentos/corpomilitar/corpomilitar.ejs', { infoReq: results23, wait: wait.length, info: req.session.user, nickname: req.session.user.nick, message: req.flash('erro'), current: pagina, paginas: totalReqPorPagina, results3, patente: req.session.user.patente, results7,

Already tried <%= results7.filter(i => i.nick === req.autor)['nPostagens'] %> or <%= results7.filter(i => i.nick === req.autor).nPostagens %> and gives undefined, while o <%= results7.filter(i => i.nick === req.autor)i.nPostagens %> gives missing ) after argument list. PS: The system is fully configured in EJS, NODEJS and MYSQL. The con queries are: con.query(SELECT *, RANK() OVER (ORDER BY id DESC) FROM req_cm LIMIT ${pular},${dadosPorPagina}, (err, results23) => { and con.query(SELECT * FROM users, (err7, results7) => {

So I would like to request help to pull the specific "nPostagens" information that respects the filter.

It is hard to get what you are asking as the code in the question is unformatted and difficult to read. However, the .filter method returns a new array. so trying to access .nPostagens would not work. If you know there will only be one item in the array, and it is an object, you can try:

results7.filter(i => i.nick === req.autor)[0].nPostagens
