the official, lightweight, and fast package manager for delux written in C99.
comes with delux linux for other distros install gcc and
- Clone the repository
- Run
makethensudo cp ./pmg /bin/finallycd / && cd etc && sudo mkdir pmg && cd pmg && sudo touch pkgls.txt - Now just type
pmg install {package-name}
At the moment it can perform an efficient clean install of a package which is cached. And then uses the cache when a module is downloaded twice. See here for features that are missing.
- Efficient version resolution which minimizes the HTTP throughput by using
{registry}/{package}/{version}instead of{registry}/{package}which has a significantly larger body size - Use of reqwest to create a HTTP connection pool
- Parallel and asyncronous HTTP requests to the PMG Host Downloading API
- Use of the
Accept: application/vnd.npm.install-v1+json; q=1.0, application/json; q=0.8, */*header which results in smaller HTTP body sizes - Duplicate avoidance by storing pre-installed versions in a HashMap for clean installs
- A global cache that symlinks point to, avoiding any file copies
- Package locks generated for each cached package, to avoid re-retrievel of the required dependencies
These are the primary functioning features required for this to pass as a "NodeJS package manager". There are plenty more quality of life and utlility features that will be neccessary:
- Expiry times for the cached packages
- Creation and maintainence of a
package.jsonin the working directory - Creation and maintainence of a
package-lock.jsonin the project directory - An
uninstallcommand - An
updatecommand - There is also an off case where some packages contain an operator at the end of their version like this
< version@2.2.3 > 1.1.2which is not tolerated by semver - Use checksums to verify file downloads
- Proper error handling everywhere
