How do I see logs on parse-server?

Question

Parse had a nice development command utility where you could read and stream logs.

Heroku has that, but it shows only Heroku logs, not Parse logs.

Is there some way to see a console.log or console.error statement now that we're all switching over to parse-server?

Answer 1

If you use PM2, it is really easy to see logs.

For my project, I have parse-server and parse-dashboard running on my server. Here is the PM2 config I use for them:

{
    "apps": [
        {
            "script": "parse-server",
            "args": "config/server.json",
            "log_file": "logs/server.log",
            "error_file": "logs/server-error.log",
            "log_date_format" : "YYYY-MM-DD HH:mm:ss Z",
            "instances": 1, 
            "watch": true,
            "ignore_watch": ["cloud", "logs"],
            "env": {
                "VERBOSE": "1"
            }
        },
        {
            "script": "parse-dashboard",
            "args": "--config config/dashboard.json",
            "log_file": "logs/dashboard.log",
            "error_file": "logs/dashboard-error.log",
            "log_date_format" : "YYYY-MM-DD HH:mm:ss Z",
            "instances": 1,
            "watch": true,
            "ignore_watch": ["cloud", "logs"]
        }
    ]
}

In my case, it is the "VERBOSE": "1" argument that allows me to see all the queries executed by parse-server.

If you want to see the logs of both parse-server and parse-dashboard, you then only have to type pm2 logs.

In my configuration, parse-server and parse-dashboard are installed globally (npm install -g parse-server and npm install -g parse-dashboard).

If you have Heroku CLI installed you can run these lines inside your project

heroku logs    

for the last 100 lines or

heroku logs --tail    

to show logs in real time

Answer 3

The latest versions of Parse dashboard have Logs page out of the box

Answer 4

I dont know about how you can see logs on Heroku, but i am able to see logs locally. What you need to do is when your run your application using command => node app.js then you will be able to see all console.log(""); statements in the console.

If you want you check this link . How to setup Parse on local machine.

I hope this helps.Thanks

here are 2 ways, in case of selfhosted parse-server:

#1 view logs by url

• create a symbolic link of your log-folder to /public/logs
• add this middleware:

app.get(/^\/logs*/,(req,res,next) => {
  if( req.url == '/logs/' || req.url == '/logs' )
    return res.redirect('/logs/parse-server.info.'+new Date().toISOString().slice(0,10))
  if( req.url.match(/parse-server\./) )
    res.set('content-type','text/plain') // lets hint the browser for a logfile
  next()
})

// *TODO* please run basic-auth middleware on /logs url

BOOM...now surfing to '/logs' will always redirect to the latest log-url. You can just modify the dates to go back in time.

#2 view realtime logs

see this package https://www.npmjs.com/package/express-logio

Answer 6

You can use request.log.info() and request.log.error() and they will be show in the parse dashboard
