node-dependencies-view's Introduction

node-dependencies-view

This repository dependency structure:

If you want to use one in your repo's README.md or anywhere else, use a link like these:

The query string arguments are set in the dot string as properties of the graph. You can use most of them. Documentation is at http://www.graphviz.org/Documentation/dotguide.pdf.

Please don't abuse this service. Since the server is a free Glitch instance it will fail if under heavy load or if you try to fetch a super huge project (GitHub caches images, so it is mostly safe to use it in README.md).

The graphs are made with Viz.js.

If you want to browse dependencies (for a lot of languages) better, you should try the Module Linker browser extension.

If you want more unrelated sugar in your GitHub README.md, you should try https://github.com/tj/gh-polls or https://ght.trackingco.de/.

Branch support

Awesome project!

Any chance you'd consider modifying the project so branches other than master could be specified? Or would you be open to accepting pull-requests that do that?

manage file not found errors

In some repositories, I deliberately exclude files containing some sensitive information (e.g. API keys stored in a params.json file).

node-dependencies-view then fails at generating the svg, producing the following error message:

{ Error: Cannot find module '../params.json'
    at Function.Module._resolveFilename (module.js:469:15)
    at resolveFileName (/tmp/node-dependencies-view/node_modules/resolve-from/index.js:17:39)
    at resolveFrom (/tmp/node-dependencies-view/node_modules/resolve-from/index.js:31:9)
    at module.exports (/tmp/node-dependencies-view/node_modules/resolve-from/index.js:34:41)
    at inspect (/tmp/node-dependencies-view/dependency-tree.js:32:22)
    at module.exports (/tmp/node-dependencies-view/dependency-tree.js:14:24)
    at download.then.then (/tmp/node-dependencies-view/graph.js:16:16) code: 'MODULE_NOT_FOUND' }
TypeError: Cannot read property 'split' of undefined
    at graph.then.dot (/tmp/node-dependencies-view/server.js:27:24)

Two possible solutions are:

skip the file not found (and possibly warn about incomplete results in the produced svg)
catch the error, and concatenate baseand req, instead on relying on function resolve.

This second solution worked well for me:

try {
	var resolved = resolve(path.dirname(file), req)
} 
catch(e) {
	var resolved = base + req
}
let rel = '.' + resolved.slice(base.length)

Would you consider a pull request for this?
