Replace unmaintained dependencies

[DeeDeeG]

Hi,

string and optimist are unmaintained. They also have vulnerability reports against them (or their own dependencies; optimist depends on an old version of minimist that is vulnerable).

Suggested replacements...

• string -->
  • underscore.string?
  • truncate?
• optimist -->
  • Wait for updated handlebars 4.x release: fix(4.x): migrate from optimist to yargs handlebars-lang/handlebars.js#1662

As far as I can tell string is only needed for the string.truncate function...

swagger-test-templates/lib/helpers.js

Line 4 in 24a1094

var strObj = require('string');

swagger-test-templates/lib/helpers.js

Line 190 in 24a1094

description = strObj(description).truncate(len - 50).s;

Could be replaced by .truncate from the underscore.string project? Or the truncate project (though the truncate project appears to round up from the cutoff length, whereas string's truncation appears to round down).

And apparently yargs is very similar to optimist... See this PR in another repo for an example of how to switch from optimist to yargs. https://github.com/wycats/handlebars.js/pull/1662/files

Suddenly realized optimist is an indirect dependency (of handlebars). So this is waiting on handlebars-lang/handlebars.js#1662.
