showRoutes function

void showRoutes(Darto app, { bool verbose = false, bool colorize = false, })

Prints all registered routes to stdout.

• verbose: appends the number of per-route middlewares when > 0
• colorize: wraps HTTP method labels in ANSI colour codes

final app = Darto().basePath('/v1');

app.get('/posts', handler);
app.get('/posts/:id', handler);
app.post('/posts', handler);

showRoutes(app, colorize: true);
// GET     /v1/posts
// GET     /v1/posts/:id
// POST    /v1/posts

Implementation

void showRoutes(
  Darto app, {
  bool verbose = false,
  bool colorize = false,
}) {
  final entries = app.routeEntries;

  if (entries.isEmpty) {
    stdout.writeln('No routes registered.');
    return;
  }

  for (final e in entries) {
    // Pad the raw method first, then wrap in colour so ANSI codes don't
    // distort the visual alignment.
    final padded = e.method.padRight(7);
    final label =
        colorize ? '$_bold${_methodColor(e.method)}$padded$_reset' : padded;

    final mwSuffix = (verbose && e.middlewareCount > 0)
        ? (colorize
            ? '  $_dim[${e.middlewareCount} mw]$_reset'
            : '  [${e.middlewareCount} mw]')
        : '';

    stdout.writeln('$label ${e.path}$mwSuffix');
  }
