npm is a package manager for the JavaScript programming language. npm, Inc. is a subsidiary of GitHub, an American multinational corporation that provides hosting for software development and version control with the usage of Git. It is the default package manager for the JavaScript runtime environment Node.js.
Go ahead and install node and any packages you may need:
$ guix package -i node js-json2
You may optionally spawn a environment seperate from your system profile:
$ guix environment node js-json2
If you insist on 100% purity for development, or testing, do:
$ guix environment node js-json2 --pure
Go ahead and install node as usual:
$ guix package -i node
and use it in your projects, as always:
$ cd project/
$ npm install
This is a little tricky; If you have too much time, do make an effort to package whatever CLI libraries that you work with, but are not available on PantherX. Here’s how to work with them anyways:
$ mkdir ~/.NPM_GLOBAL
$ cd ~/.NPM_GLOBAL
Now install whatever package / CLI you need:
$ npm install @vue/cli
$ npm install @vue/cli-init
and add it at the bottom of your your ~/.bash_profile like so:
# ~/.bash_profile
$ alias vue=/home/franz/.NPM_GLOBAL/node_modules/.bin/vue
$ alias vue-cli/home/franz/.NPM_GLOBAL/node_modules/.bin/vue-cli
Lising each binary manually is a bit of a conservative approach, but may work well if it’s mostly self-contained. Like vue CLI.
That’s it. You can now run this CLI globally:
$ vue --version
@vue/cli 4.5.7
We’ll set these up for local development but with minor modifications you can run this on a server too.
Login as root before you continue.
su - root
To configure this, you will need to do two things:
databases package and service module.postgresql-service-type to your servicesOpen /etc/system.scm:
(use-modules (gnu)
(gnu system)
(px system)
...
;; Add this line
(gnu packages databases))
;; Add this line
;; If 'user-service-modules' already exists, just add 'databases' to it
(use-service-modules databases)
(px-desktop-os
(operating-system
...
))
Modify services:
Refer to https://www.postgresql.org/docs/13/auth-pg-hba-conf.html for more information on pg_hba.conf and database authentication options.
(services (cons* (service postgresql-service-type
(postgresql-configuration
(config-file
(postgresql-config-file
(hba-file
(plain-file "pg_hba.conf"
"
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 md5"))))
(postgresql postgresql-10)))
%px-desktop-services))
This will ensure that any user can connect do any database via unix socker or 127.0.0.1 for ease.
All we need to add is (service redis-service-type).
(services (cons* (service postgresql-service-type
(postgresql-configuration
(config-file
(postgresql-config-file
(hba-file
(plain-file "pg_hba.conf"
"
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 md5"))))
(postgresql postgresql-10)))
;; Add this line
(service redis-service-type)
%px-desktop-services))
To configure this, you will need to do two things:
web package and service module.nginx-service-type to your services(1) Create a self-signed certificate:
openssl req -newkey rsa:4096 \
-x509 \
-sha256 \
-days 3650 \
-nodes \
-out ~/example.crt \
-keyout ~/example.key
Open nano /etc/system.scm:
(2) Import the web package and service module
(use-modules (gnu)
(gnu system)
(px system)
...
(gnu packages databases)
;; Add this line
(gnu packages web))
(use-service-modules databases web)
(px-desktop-os
(operating-system
....
))
(3) Add the nginx-service-type to your services
Modify services to look like this:
This is where your self-signed certificate and key at /root/... is used. (Don’t do this in production. Use Certificate Services instead.)
(services (cons* (service postgresql-service-type
(postgresql-configuration
(config-file
(postgresql-config-file
(hba-file
(plain-file "pg_hba.conf"
"
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 md5"))))
(postgresql postgresql-10)))
(service redis-service-type)
;; Add these lines
(service nginx-service-type
(nginx-configuration
(server-blocks
(list (nginx-server-configuration
(server-name '("example.com"))
(ssl-certificate "/root/example.crt")
(ssl-certificate-key "/root/example.key")
(locations
(list
(nginx-location-configuration
(uri "/")
(body '("proxy_pass http://localhost:4000;"))))))))))
%px-desktop-services))
To actually test this locally, we need to also modify the hosts file and add 127.0.0.1 example.com. We also do this in /etc/system.scm:
...
(px-desktop-os
(operating-system
(host-name "panther")
(timezone "Europe/Berlin")
(locale "en_US.utf8")
;; Add these lines
(hosts-file
(plain-file "hosts"
"
127.0.0.1 localhost panther
::1 localhost panther
127.0.0.1 example.com"))
...
))
To apply all these changes, reconfigure:
guix system reconfigure /etc/system.scm
Now you should have PostgreSQL, Redis and Nginx running.
Go back to your user account.
exit
Install node:
guix package -i node
and run your application (for ex. express server) on port 4000.
Just open https://example.com/ in Firefox, skip the certificate warning and you should see your application.
To revert, simply remove the changes from /etc/system.scm and reconfigure with
guix system reconfigure /etc/system.scm
You can also start and stop or restart services:
su - root
herd status # get a list of all running services
herd stop nginx
herd start nginx
herd restart nginx
