MathJax is a JavaScript display engine for mathematics that works in all browsers. However, the Vapor Leaf and MathJax combination does not render math expressions correctly.
The example code for this issue is in the GitHub VaporExamplesLab/issue-vapor-leaf-mathjax repository. Also submitted vapor/leaf/issues/133.
vapor new issue-vapor-leaf-latex --web
cd issue-vapor-leaf-latex
vapor update -yroutes.swift (Add math test route.)
// :ADD: math
router.get("math") { req -> Future<View> in
return try req.view().render("math")
}Resources/Views/base.leaf (Add MathJax to existing base.leaf.)
