I am trying to use ajax-seo for an Angularjs app to serve html compiled content from a PhantomJS webserver`. But it's not rendering the complete page. It's just giving the following response
<html><head></head><body></body></html>
I have followed the instructions well but no luck so far. So I'd like to know whether PhantomJS supports ES6 or not, because my app is in ES6.
PhantomJS 2.1.1 only supports about 10% of ECMAScript 6, which might not be enough to properly render your page.
Here is a slightly more detailed result based on https://kangax.github.io/compat-table/es6/:
Overall coverage: 10% > Array is subclassable: 0/11 > Array static methods: 0/11 > Array.prototype methods: 0/10 > Date.prototype[Symbol.toPrimitive]: No > Function is subclassable: 0/6 > HTML-style comments: Yes > Map: 0/19 > Math methods: 1/17 > Number properties: 0/7 > Object static methods: 0/4 > Object static methods accept primitives: 0/10 > Object.prototype.__proto__: 6/6 > Promise: 0/8 > Promise is subclassable: 0/4 > Proxy: 0/34 > Proxy, internal 'defineProperty' calls: 0/2 > Proxy, internal 'deleteProperty' calls: 0/6 > Proxy, internal 'get' calls: 0/36 > Proxy, internal 'getOwnPropertyDescriptor' calls: 0/4 > Proxy, internal 'ownKeys' calls: 0/3 > Proxy, internal 'set' calls: 0/11 > Reflect: 0/20 > RegExp "y" and "u" flags: 0/5 > RegExp is subclassable: 0/4 > RegExp syntax extensions: 8/8 > RegExp.prototype properties: 0/6 > RegExp.prototype.compile: Yes > Set: 0/19 > String static methods: 0/2 > String.prototype HTML methods: 3/3 > String.prototype methods: 0/10 > Symbol: 0/11 > Unicode code point escapes: 0/2 > WeakMap: 0/12 > WeakSet: 0/11 > __proto__ in object literals: 1/5 > arrow functions: 0/13 > block-level function declaration: No > class: 0/24 > const: 1/16 > default function parameters: 0/7 > destructuring, assignment: 0/24 > destructuring, declarations: 0/22 > destructuring, parameters: 0/23 > for..of loops: 0/9 > function "name" property: 3/17 > generators: 0/27 > let: 0/12 > miscellaneous: 2/10 > miscellaneous subclassables: 0/6 > new.target: 0/2 > non-strict function semantics: 2/3 > object literal extensions: 0/6 > octal and binary literals: 0/4 > own property order: 4/7 > proper tail calls (tail call optimisation): 0/2 > prototype of bound functions: 0/5 > rest parameters: 0/5 > spread (...) operator: 0/15 > super: 0/8 > template literals: 0/5 > typed arrays: 19/46 > well-known symbols: 0/26
