How to deploy Next.js with GraphQL backend on Zeit Now? - graphql

I have an Next.js/Express/Apollo GraphQL app running fine on localhost.
I try to deploy it on Zeit Now, and the Next.js part works fine, but the GraphQL backend fails because /graphql route returns:
502: An error occurred with your deployment
Code: NO_STATUS_CODE_FROM_LAMBDA
My now.json looks like:
{
"version": 2,
"builds": [
{ "src": "next.config.js", "use": "#now/next" },
{ "src": "server/server.js", "use": "#now/node" }
],
"routes": [
{ "src": "/api/(.*)", "dest": "server/server.js" },
{ "src": "/graphql", "dest": "server/server.js" }
]
}
Suggestions?

Here’s a complete example of Next.js/Apollo GraphQL running both on Zeit Now (as serverless function/lambda) and Heroku (with an Express server):
https://github.com/tomsoderlund/nextjs-pwa-graphql-sql-boilerplate

I was getting that error until I found on a solution on the Wes Bos slack channel.
The following worked for me, but it's possible you could be getting that error for a different reason.
I'm not sure why it works.
You can see it working here
cd backend
Run npm install graphql-import
Update scripts in package.json:
"deploy": "prisma deploy --env-file variables.env&& npm run writeSchema",
"writeSchema": "node src/writeSchema.js"
Note: For non windows users make sure to place space before &&
Create src/writeSchema.js:
const fs = require('fs');
const { importSchema } = require('graphql-import');
const text = importSchema("src/generated/prisma.graphql");
fs.writeFileSync("src/schema_prep.graphql", text)
Update src/db.js:
const db = new Prisma({
typeDefs: __dirname + "/schema_prep.graphql",
...
});
Update src/createServer.js:
return new GraphQLServer({
typeDefs: __dirname + '/schema.graphql',
...
});
Update src/schema.graphql:
# import * from './schema_prep.graphql'
Create now.json
{
"version": 2,
"name": "Project Name",
"builds": [
{ "src": "src/index.js", "use": "#now/node-server" }
],
"routes": [
{ "src": "/.*", "dest": "src/index.js" }
],
"env": {
"SOME_VARIABLE": "xxx",
...
}
}
Run npm run deploy to initially create schema_prep.graphql.
Run now
Another reply said this:
You should not mix graphql imports and js/ts imports. The syntax on the graphql file will be interpreted by graphql-import and will be ignored by ncc (the compiler which reads the __dirname stuff and move the file to the correct directory etc)
In my example 'schema_prep.graphql' is already preprocessed with the imports from the generated graphql file.
Hopefully this helps.

Cannot use import statement outside a module
What could be the problem here? I have another, similar app and it is all working fine.
I figured it out. It was the problem with hooks folder in the project root directory.
I don't know why this happened but after removing the plugin (the hooks directory was not removed) I removed the hooks folder manually and then installed the plugin again - the problem disappeared.

Lighthouse shows Does not respond with a 200 when offline in pwa but offline mode works

Quick question:
While the browser identifies my application as a valid PWA, as well as shows the install popup on the mobile browser. When it is audited in lighthouse, it shows Does not respond with a 200 when offline. I have validated that my app shell is cached from application(screenshots attached).
Details and Background:
I have built PWA on laravel using js and jquery. For asset compiling, I am using laravel mix and for PWA framework, I am using workbox. Also just to be clear I am not using any SPA framework/library .
In short I have built a custom spa using simpler components.
For PWA part this I am using workbox along with laravel mix.
Here are my service worker, manifest.json and mix file. note that I use sw.js and generate prod-sw.js using laravel-mix. This prod-sw.js is used in production
webpack.mix.js
require('laravel-mix-versionhash');
const mix = require('laravel-mix');
const workboxPlugin = require('workbox-webpack-plugin');

publicPath: ''
},
plugins: [
new workboxPlugin.InjectManifest({
swSrc: 'sw.js', // more control over the caching
swDest: 'prod-sw.js', // the service-worker file name
importsDirectory: 'service-worker', // have a dedicated folder for sw files

It works offline for me just in devTools but not fully offline and lighthouse has given the same results as yours.

Ionic 3 Cordova ajax calls fail on Windows 10 (UWP)

I have attempted to ask this previously, buy got no real answers, and have now been struggling for over a month.
I just cannot get my ajax calls to work on an Ionic 3 Cordova application built for a Windows 10 UWP. They can access localhost, but not any outside connections.
The application works fine on both Android and iOS.
I am trying to test this locally on my dev machine. I use a certificate (bought) to sign the application, install this certificate, build the application for Windows, and am able to open up the built CordovaApp.Windows10_1.0.1.1_x86.appxupload, and then double click the embedded CordovaApp.Windows10_1.0.1.1_x86.appx file to install, which completes successfully. The install indicates the app need internet access.
In the config.xml, I have the following tags, as suggested elsewhere...
<allow-navigation href="*" />
<access origin="*" />
However, when I run, the http.get call just returns 0 with no other information. I can run in Visual Studio, and look at the returned error object, and get no further info, apart from this 0 return.
I have run fiddler, enabled the https decryption as explained here, but all I see in the response header is
HTTP/1.0 200 Connection Established
FiddlerGateway: Direct
StartTime: 13:44:21.686
Connection: close
The result in the main view actually shows 200, so I don't think this is showing me anything real.
I am at a complete loss. I have no where else to search. What could I be missing?
Should I be able to use external ajax on a Windows 10 machine, when I have sideloaded the application as here? I haven't tried from the store yet, as I don't want to upload until I know it works.
Any suggestions desperately welcomed. Surely someone has had an Ionic 3 application accessing external ajax working?
Thanks in advance for any help
[UPDATE 1]
If I run the application on the same machine, just using Ionic serve (so it just runs in the browser rather than hosted in the UWP), the ajax calls also work fine.
[UPDATE 2]
I have now created a Cordova application using the Visual Studio template, so taking all other frameworks out of the equation.
I used vanilla JavaScript to do my rest call...
document.addEventListener('deviceready', callUrl, false);
function callUrl() {
console.log('callUrl');
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://myserveraddress.com/myapp/testroute');
xhr.send(null);
xhr.onreadystatechange = function () {
var DONE = 4; // readyState 4 means the request is done.
var OK = 200; // status 200 is a successful return.
if (xhr.readyState === DONE) {
if (xhr.status === OK)
console.log(xhr.responseText);
} else {
console.log('Error: ' + xhr.status);
}
}
};
I run this in the debugger, and even here I get an error (status code of 0).
Another thing I noticed when I open up the build package and look at the cordova_plugins.js file..
My Ionic app has the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [
{
"id": "cordova-plugin-console.logger",
"file": "plugins/cordova-plugin-console/www/logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"cordova.logger"
]
},
{
"id": "cordova-plugin-console.console",
"file": "plugins/cordova-plugin-console/www/console-via-logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"console"
]
},
{
"id": "cordova-plugin-device.device",
"file": "plugins/cordova-plugin-device/www/device.js",
"pluginId": "cordova-plugin-device",
"clobbers": [
"device"
]
},
{
"id": "cordova-plugin-device.DeviceProxy",
"file": "plugins/cordova-plugin-device/src/windows/DeviceProxy.js",
"pluginId": "cordova-plugin-device",
"merges": [
""
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreen",
"file": "plugins/cordova-plugin-splashscreen/www/splashscreen.js",
"pluginId": "cordova-plugin-splashscreen",
"clobbers": [
"navigator.splashscreen"
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreenProxy",
"file": "plugins/cordova-plugin-splashscreen/www/windows/SplashScreenProxy.js",
"pluginId": "cordova-plugin-splashscreen",
"runs": true
},
{
"id": "cordova-plugin-statusbar.statusbar",
"file": "plugins/cordova-plugin-statusbar/www/statusbar.js",
"pluginId": "cordova-plugin-statusbar",
"clobbers": [
"window.StatusBar"
]
},
{
"id": "cordova-plugin-statusbar.StatusBarProxy",
"file": "plugins/cordova-plugin-statusbar/src/windows/StatusBarProxy.js",
"pluginId": "cordova-plugin-statusbar",
"runs": true
},
{
"id": "ionic-plugin-keyboard.KeyboardProxy",
"file": "plugins/ionic-plugin-keyboard/src/windows/KeyboardProxy.js",
"pluginId": "ionic-plugin-keyboard",
"clobbers": [
"cordova.plugins.Keyboard"
],
"runs": true
}
];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-console": "1.0.5",
"cordova-plugin-device": "1.1.4",
"cordova-plugin-splashscreen": "4.0.3",
"cordova-plugin-statusbar": "2.2.2",
"cordova-plugin-whitelist": "1.3.1",
"ionic-plugin-keyboard": "2.2.1"
};
// BOTTOM OF METADATA
});
Now, I notice every plugin in the module.exports.metadata also has an entry in the module.exports EXCEPT for cordova-plugin-whitelist!
If I open the same file for the Corvoda application created in VS, I see the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-whitelist": "1.2.2"
};
// BOTTOM OF METADATA
});
So this has nothing else for the whitelist plugin as well
Could there be something missing here?? Could this white-list plugin not be installed correctly?
I had a similar situation where my ajax calls worked fine in TEST, but when I moved to PROD, they would fail.
The answer was finally tracked down as a missing intermediary certificate on the server I was trying to access. TEST had the cert, PROD did not.
I hope this helps.

How do I use CloudFormation resources in a Lambda function?

I have added a Redis ElastiCache section to my s-resource-cf.json (a CloudFormation template), and selected its hostname as an output.
"Resources": {
...snip...
"Redis": {
"Type": "AWS::ElastiCache::CacheCluster",
"Properties": {
"AutoMinorVersionUpgrade": "true",
"AZMode": "single-az",
"CacheNodeType": "cache.t2.micro",
"Engine": "redis",
"EngineVersion": "2.8.24",
"NumCacheNodes": "1",
"PreferredAvailabilityZone": "eu-west-1a",
"PreferredMaintenanceWindow": "tue:00:30-tue:01:30",
"CacheSubnetGroupName": {
"Ref": "cachesubnetdefault"
},
"VpcSecurityGroupIds": [
{
"Fn::GetAtt": [
"sgdefault",
"GroupId"
]
}
]
}
}
},
"Outputs": {
"IamRoleArnLambda": {
"Description": "ARN of the lambda IAM role",
"Value": {
"Fn::GetAtt": [
"IamRoleLambda",
"Arn"
]
}
},
"RedisEndpointAddress": {
"Description": "Redis server host",
"Value": {
"Fn::GetAtt": [
"Redis",
"Address"
]
}
}
}
I can get CloudFormation to output the Redis server host when running sls resources deploy, but how can I access that output from within a Lambda function?
There is nothing in this starter project template that refers to that IamRoleArnLambda, which came with the example project. According to the docs, templates are only usable for project configuration, they are not accessible from Lambda functions:
Templates & Variables are for Configuration Only
Templates and variables are used for configuration of the project only. This information is not usable in your lambda functions. To set variables which can be used by your lambda functions, use environment variables.
So, then how do I set an environment variable to the hostname of the ElastiCache server after it has been created?
You can set environment variables in the environment section of a function's s-function.json file. Furthermore, if you want to prevent those variables from being put into version control (for example, if your code will be posted to a public GitHub repo), you can put them in the appropriate files in your _meta/variables directory and then reference those from your s-function.json files. Just make sure you add a _meta line to your .gitignore file.
For example, in my latest project I needed to connect to a Redis Cloud server, but didn't want to commit the connection details to version control. I put variables into my _meta/variables/s-variables-[stage]-[region].json file, like so:
{
"redisUrl": "...",
"redisPort": "...",
"redisPass": "..."
}
…and referenced the connection settings variables in that function's s-function.json file:
"environment": {
"REDIS_URL": "${redisUrl}",
"REDIS_PORT": "${redisPort}",
"REDIS_PASS": "${redisPass}"
}
I then put this redis.js file in my functions/lib directory:
module.exports = () => {
const redis = require('redis')
const jsonify = require('redis-jsonify')
const redisOptions = {
host: process.env.REDIS_URL,
port: process.env.REDIS_PORT,
password: process.env.REDIS_PASS
}
return jsonify(redis.createClient(redisOptions))
}
Then, in any function that needed to connect to that Redis database, I imported redis.js:
redis = require('../lib/redis')()
(For more details on my Serverless/Redis setup and some of the challenges I faced in getting it to work, see this question I posted yesterday.)
update
CloudFormation usage has been streamlined somewhat since that comment was posted in the issue tracker. I have submitted a documentation update to http://docs.serverless.com/docs/templates-variables, and posted a shortened version of my configuration in a gist.
It is possible to refer to a CloudFormation output in a s-function.json Lambda configuration file, in order to make those outputs available as environment variables.
s-resource-cf.json output section:
"Outputs": {
"redisHost": {
"Description": "Redis host URI",
"Value": {
"Fn::GetAtt": [
"RedisCluster",
"RedisEndpoint.Address"
]
}
}
}
s-function.json environment section:
"environment": {
"REDIS_HOST": "${redisHost}"
},
Usage in a Lambda function:
exports.handler = function(event, context) {
console.log("Redis host: ", process.env.REDIS_HOST);
};
old answer
Looks like a solution was found / implemented in the Serverless issue tracker (link). To quote HyperBrain:
CF Output variables
To have your lambda access the CF output variables you have to give it the cloudformation:describeStacks access rights in the lambda IAM role.
The CF.loadVars() promise will add all CF output variables to the process'
environment as SERVERLESS_CF_OutVar name. It will add a few ms to the
startup time of your lambda.
Change your lambda handler as follows:
// Require Serverless ENV vars
var ServerlessHelpers = require('serverless-helpers-js');
ServerlessHelpers.loadEnv();
// Require Logic
var lib = require('../lib');
// Lambda Handler
module.exports.handler = function(event, context) {
ServerlessHelpers.CF.loadVars()
.then(function() {
lib.respond(event, function(error, response) {
return context.done(error, response);
});
})
};

How to set up Browserify with Elixir and Browserify Shim on Laravel 5?

I am trying to set up Browserify with Elixir and Browserify Shim on Laravel 5.2 to use Gulp with my JavaScript files, but I didn't have much luck so far. This should be pretty straightforward to do, but it isn't.
Here is my package.json
{
"private": true,
"devDependencies": {
"gulp": "^3.8.8"
},
"dependencies": {
"bootstrap-sass": "^3.0.0",
"browserify-shim": "^3.8.12",
"jquery": "^2.2.0",
"jquery-ui": "^1.10.5",
"laravel-elixir": "^4.0.0"
},
"browser": {
"app": "./resources/assets/js/app.js",
"utils": "./resources/assets/js/utils.js",
},
"browserify": {
"transform": [
"browserify-shim"
]
},
"browserify-shim": {
"app": {
"depends": [
"jquery:$",
"utils:Utils"
]
},
"utils": {
"depends": [
"jquery:$"
]
},
}
}
gulpfile.js
var elixir = require('laravel-elixir');
elixir(function (mix) {
mix.browserify('main.js', './public/js/bundle.js');
});
Entry script main.js looks like this:
var $ = require('jquery');
var Utils = require('utils');
var App = require('app');
app.js
var App = {
init: function(){
console.log(Utils);
Utils.doSomething();
}
//other methods
};
In short: Utils depends on $, and App depends on both $ and Utils.
When I hit gulp from terminal, bundle.js is correctly created. All scripts are wrapped up in Browserify code (as expected). Each script has all included dependencies, like I configured in package.json so this part looks good as well.
The problem is that all my included dependencies are empty objects. For example, Utils in app.js is empty, and I get an error when I try to call its method "doSomething". Console log prints out an empty object "{}" instead of real object. The only correctly included script is jQuery and it's not an empty object.
What could be wrong here? Do I need to make some changes in my JS files or in configuration to make this work? It looks like I'm pretty close to the solution, but it still does not work and I can't use it at all.
It is the easiest solution to directly use 'exports' from browserify-shim property:
"browserify-shim": {
"app": {
"exports": "App",
"depends": [
"jquery:$",
"utils:Utils"
]
},
"utils": {
"exports": "Utils",
"depends": [
"jquery:$"
]
},
}
Take a look at this repo which I believe shows the fixed version of your app. The issue is that your app.js and utils.js modules aren't exporting anything to their respective require calls. One option is to add a line like:
module.exports = App;
to the bottom of your app.js file, and the equivalent to the bottom of your utils.js file. You'll see if you test the repo that badapp doesn't have this line and produces the exact behavior you're describing.
See this answer for an explanation of the issue.
