To log response body with Node Express, we use express-winston.
For instance, we write
expressWinston.requestWhitelist.push("body");
expressWinston.responseWhitelist.push("body");
app.use(
expressWinston.logger({
transports: [
new winston.transports.Console({
json: true,
colorize: true,
}),
],
meta: true,
msg: "HTTP {{req.method}} {{req.url}}",
expressFormat: true,
colorStatus: true,
ignoreRoute: (req, res) => {
return false;
},
})
);
to add a logger with expressWinston.logger.
The meta option lets us set whether to log meta data.
msg is the log entry format.
expressFormat lets us set whether to use the default formatting.
colorStatus lets us set whether to color the log entry.
ignoreRoute lets us set the routes to skip logging for.
