Hi there! Do you have that website hosted publicly anywhere that we could access and test? If so, feel free to email it to me at todd@prerender.io. I’d love to help figure out what’s going on here.

SkyRooms · April 26, 2017, 2:18pm

PreRender.io is awesome, there’s not a decent guide out there for installation, but once you get it working, it’s really cool and easier to setup than I thought lol.

prerender · April 26, 2017, 6:21pm

Thanks for the feedback We’ll have to improve our documentation!

SkyRooms · April 27, 2017, 12:13am

I’m not so certain it’s the documentation; Meteor itself is a very difficult system to learn.

For example, my settings.json has to be on ONE LINE to get it working. No where on the net does it say to do this. Even when you bundle and deploy, it’ll go haywire. So, that means the prerender.io service simply won’t work.

The whole issue of ?fragment_cache or whatever is soooo confusing to learn. I mean, it makes sense 3 weeks after studying the material and trial and error, like pretty obvious now - but it’s still whacky.

Anyway, just wanted to put some solid defense in for prerender, I bet theres a lot of folks who get stuck and abandon ship. You shouldn’t. Prerender is fantastic once it works.

liu0fanyi · April 27, 2017, 2:08am

Thanks a lot, I have got email from you!

[Error] SyntaxError: Unexpected keyword ‘const’
(anonymous function) (431789012886b43af9745cefbf7fed5eeac6b4ac.js, line 95)

Are you using ES6 javascript in your code? If so, our rendering engine (PhantomJS v2.1.1) doesn’t currently support ES6. Can you use Babel to transpile that to ES5?

But in meteor there has default packages transpile app to ES5

ecmascript 0.7.2* Compiler plugin that supports ES2015+ in all .js files
es5-shim 4.6.15 Shims and polyfills to improve ECMAScript 5 support

So, I go back here…

liu0fanyi · April 27, 2017, 1:11pm

I have tried prerenderio with meteor official todo web app.
prerender is ok…

Looks like something wrong with my code…
It run well in production, and error info is hard to trace…
What could I do next…

SkyRooms · April 27, 2017, 6:22pm

Make sure your PreRender dashboard is connecting to your site. You’ll see pages generating, and PR will tell you there has been a connection

liu0fanyi · April 28, 2017, 3:34pm

Hi, Thanks for your help…
I have found something wrong with my codes…
When I use ali-oss package in meteor-file like this

import oss 		from 'ali-oss';

I will get those error info…
Delete this import, PR is ok…

Meteor has babel default right?
This package use es6 character， like Generator Function
What could I do next?
I don’t know how to config babel in meteor just for this package…
Want any suggestions…
Thanks!

liu0fanyi · April 28, 2017, 4:08pm

I have found the error… I should require package in Meteor.server…
