For anyone out there that finds this question looking to do this in WebGL, here's the WebGL equivalent:

var program = gl.createProgram();
// ...attach shaders, link...

var na = gl.getProgramParameter(program, gl.ACTIVE_ATTRIBUTES);
console.log(na, 'attributes');
for (var i = 0; i < na; ++i) {
  var a = gl.getActiveAttrib(program, i);
  console.log(i, a.size, a.type, a.name);
}
var nu = gl.getProgramParameter(program, gl.ACTIVE_UNIFORMS);
console.log(nu, 'uniforms');
for (var i = 0; i < nu; ++i) {
  var u = gl.getActiveUniform(program, i);
  console.log(i, u.size, u.type, u.name);
}
