fyn

fyn

fyn is the package manager for fynpo, a zero setup monorepo manager for node.js.

It treats your disk as a registry so you can develop, publish, and test all your packages using local copies directly.

Quick Start

Interested in giving it a quick test? Just install and run it on your project:

npm i -g fyn
cd <your-project>
fyn

Want to add a package on your local disk as a dependency to your project? Do this:

fyn add ../another-package

To see detailed stats about any package, use the stat command:

fyn stat lodash

• It can read and use some settings from your .npmrc.
• It can use npm-shrinkwrap.json or package-lock.json files.

Configuring fyn

fyn options can be listed in help:

fyn --help

fyn loads config from CWD/.fynrc, CWD/.npmrc, ~/.fynrc, and ~/.npmrc in this specified order, from highest to lowest priority.

From .npmrc, only fields registry, @<scope>:registry,email, and _auth are read.

.fynrc file can be an ini or YAML format. For the YAML format, the first line must be ---.

Below is an YAML example, with all the options set to their default values:

---
registry: https://registry.npmjs.org
"@scope:registry": https://registry.custom.com
offline: false
forceCache: false
lockOnly: false
progress: normal
logLevel: info
production: false
centralStore: false

Or as an ini:

registry=https://registry.npmjs.org
@scope:registry=https://registry.custom.com
offline=false
forceCache=false
lockOnly=false
progress=normal
logLevel=info
production=false
centralStore=false

Thank you npm

Node Package Manager is a very large and complex piece of software. Developing fyn was 10 times easier because of the generous open source software from the community, especially the individual packages that are part of npm.

Other than benefiting from the massive package ecosystem and all the documents from npm, these are the concrete packages from npm that fyn is using directly.

• node-tar - for untaring tgz files.
• semver - for handling Semver versions.
• pacote - for retrieving npm package data.
• ini - for handling ini config files.
• npm-packlist - for filtering files according to npm ignore rules.
• npm-lifecycle - for npm_config env and offering run as a convenience.
• npmlog - for offering the run command as a convenience.
• And all the other packages they depend on.
