COPY TO STDOUT with node.js

Question

I'm trying to make a query in javascript with node.js but nothing happens..

Here is the following query: "COPY tag_7z8eq73 to STDOUT WITH CSV HEADER"

It is working with psql, I can see the full table in result in the terminal of the psql shell.

Here is the function that i'm calling when I click on a button :

async function exportDatabase(req, res){
return db.any("COPY tag_7z8eq73 to STDOUT WITH CSV HEADER")
.then(rows => {
        res.json(rows)
    })
    .catch(error => {
        console.log(error)
    });   }

I guess I'm supposed to see something in the debug console of my code editor (here VScode) but there is nothing that happens.

Anyone have an idea ?

最后，我没有使用复杂的“COPY TO”命令行，而是“选择”数据库，将其推送到数组中，将其转换为 json 并使用“vue-json-to-csv”插件创建一个 csv 文件。
