Change "start": "nodemon --exec npm run babel-node index.js" to "start": "node ./node_modules/babel-cli/bin/babel-node.js --presets env index.js",
You can easily install MongoDB in Arch-base Linux by following commands:
pamac search -a mongodb-bin
pamac info -a mongodb-bin
And, then build and install with (this can be done after manually cloning too) -
pamac build mongodb-bin
As shown below, the service does not run and has an error. This is a file access and execution error. The easiest way is as follows:
[max@base first-nodejs-apollo-graphql]$ sudo systemctl status mongodb
● mongodb.service - High-performance, schema-free document-oriented database
Loaded: loaded (/usr/lib/systemd/system/mongodb.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Thu 2020-12-24 05:16:07 +0330; 4s ago
Modify /usr/lib/systemd/system/mongodb.service file.
However, manipulating these accesses is not recommended.
Anyway, You can change user from mongodb to root to solve this problem:
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
[Service]
User=root
ExecStart=/usr/bin/mongod --quiet --config /etc/mongodb.conf
[Install]
WantedBy=multi-user.target
And then:
$ systemctl daemon-reload
$ sudo systemctl restart mongodb
$ sudo systemctl status mongodb
● mongodb.service - High-performance, schema-free document-oriented database
Loaded: loaded (/usr/lib/systemd/system/mongodb.service; enabled; vendor preset: disabled)
Active: active (running) since Thu 2020-12-24 05:16:39 +0330; 2s ago
$ sudo systemctl enable mongodb
