Meteor atmosphere package source - meteor

Am I naive or is there really no way to download the source of a meteor package as the project was originally created?
(function () {
////////////////////////////////////////////////////////////////////////////////////////////////
// //
// packages/iron:router/lib/route.js //
// //
////////////////////////////////////////////////////////////////////////////////////////////////
//
var Url = Iron.Url; // 1
var MiddlewareStack = Iron.MiddlewareStack; // 2
var assert = Iron.utils.assert; // 3
// 4
/*****************************************************************************/ // 5
/* Both */ // 6
/*****************************************************************************/ // 7
Everything I download seems to be been processed through some kind of preprocessor. It seems to all be there and in order but what's the deal? Is there a way to ask for the unprocessed source?

You can download the package from the git repository of that package.
For editing the package just copy the repository to packages folder.
Don't forgot to add package name in package file.

Edge browser Native File System removeEntry use

I'm working with the newest version of Edge (Canary release 86.0.615.0) and I can get the new Native File System API showOpenFilePicker to let me access files but I can't find a reference to the directoryHandle functions including the removeEntry function if the user elects to remove the file. Am I missing a special flag? I have an Origin-Tracker code and I also have the experimental flag set for the Native File System API.
If you have a directory handle, you can delete files or folders as in the example below:
// Delete a file.
await directoryHandle.removeEntry('Abandoned Projects.txt');
// Recursively delete a folder.
await directoryHandle.removeEntry('Old Stuff', { recursive: true });
You can obtain a directory handle from the picker:
const directoryHandle = await window.showDirectoryPicker();
To iterate over the entries of a directory, you can use the code snippet below:
for await (const entry of directoryHandle.values()) {
console.log(entry.kind, entry.name);
}

Using modules in Meteor.js with Typescript

Folks, I'm trying to do something that I thought ought to be simple, but I must be doing something wrong. I'm trying to simply have a clear structure in my meteor application which uses Typescript.
Here are my requirements:
All interfaces are available in both client and server
Some class implementations are only available on the server
I don't want to rely on file load order for my application to work properly
I need my own module to not clash with global objects (such as the Position class for example)
I need to have one monolithic include file for server, one for both client and server and one for client (don't want to have 10s of includes on top of my files)
The setup that I have right now is this
server
server-book.ts
client
shared
collections.ts
definitions
server
include.d.ts (includes all .d.ts files in this folder)
server-book.d.ts (server specific implementation of book)
client
shared
include.d.ts (includes all .d.ts files here)
book.d.ts (book interface definition)
collections.d.ts
In each .d.ts file I have
module MyModule {
interface Bla {}
};
In each .ts file that defines a class I have:
module MyModule {
export class MyBla implements Bla {};
}
All .d.ts files generated for classes are generated by tsc -d.
No .ts files are being included via ///<reference> rather only .d.ts files.
Now, when I run this, I get an error that MyModule is undefined:
/// <reference path="shared/include.d.ts"/>
/// <reference path="server/include.d.ts"/>
Meteor.startup(() => {
var temp = new MyModule.ServerBook();
});
The error occurs right on MyModule.
What am I doing wrong? What should be the proper setup here?
Thanks!
I have dealt with this issue on my blog. I decided to use the evil eval command, since it gave me the easiest possibility of using modules till something more sophisticated appears.
File /lib/foo.ts is position in the subdirectory since it has to be loaded before Bar.
eval('var Hugo = (this.Hugo || (this.Hugo = {})'); // this will override the automatically emitted var Hugo and assigns it with globally defined Hugo module
module Hugo {
export class Foo {
foo():string {
return 'foo'
}
}
}
File /bar.ts
/// <reference path="lib/foo.ts"/>
eval('var Hugo = (this.Hugo || (this.Hugo = {})'); // this will override the automatically emitted var Hugo and assigns it with globally defined Hugo module
module Hugo {
export class Bar extends Foo {
bar () : string {
return 'bar';
}
}
}
File /test.ts
/// <reference path="lib/foo.ts"/>
/// <reference path="bar.ts"/>
var m = new Hugo.Bar();
console.log(m.bar());
console.log(m.foo());
As mentioned here, for classes, the solution is even simpler:
class ExportedClass {
variable : int;
}
this.ExportedClass = ExportedClass;
Definition files should use the declare keyword. You would normally get an error if you didn't use this keyword.
declare module MyModule {
export interface Bla {}
}
And
declare module MyModule {
export class MyBla implements Bla {
}
}
It is also worth checking that the ServerBook class has the export keyword (just like MyBla in your examples).
After lot of trial and errors, here are my findings so far :
Using typescript "module" keyword doesn't get well with Meteor. I think at the moment you cannot use it (or the workarounds are too complicated for me).
However, here is what you can do :
Let say that you have package A where you want to define a class ClassToExport which you want to make public.
class ClassToExport {
getFoo(){
return "foo";
}
}
Please note that you can't write this.ClassToExport = ClassToExport and
api.export('ClassToExport') or else ClassToExport won't be available in the global scope of package A, hence the need for a module/namespace for exporting your class, which we will see next.
Now, for the class to be available for the consumers of your package, you have to create a namespace, which will be the equivalent of the "module" typescript keyword for internal module.
So let's write :
declare var packageA; //so that the compiler doesn't complain about undeclared var
packageA = packageA || {}; //so that this namespace can be reused for the entire package
packageA.ClassToExport = ClassToExport; //the actual export
Now, don't forget to write
api.export('packageA') in the package.js of package A
If you have a package B where you want to use ClassToExport, you write in package B:
var cte = new packageA.ClassToExport();
without forgetting to api.use package A in package B's package.js
If you don't want to write the namespace each time you use the class, you can also write var ClassToExport = packageA.ClassToExport; at the top of your using file.
If you need a global class for you package only, without exporting it, then you can do instead just :
this.ClassToExport = ClassToExport
and again don't write api.export('ClassToExport'), or it won't be available in the package anymore.
This way, i think the features (export/ import) of internal typescript modules are there.
If you are not afraid of gulp build, I have prepared a typescript boilerplate project which allows you to comfortably use typescript from within your app, not depending on packages.

Random idea, what about extend Meteor instead of Window.
Meteor.yournamespace = Meteor.yournamespace || {};
Meteor.yournamespace.myclass = new MyClass();
or
Meteor.yournamespace.MyClass = MyClass();
I think this is less invasive than go directly to the window object IMHO. my two cents.
now you can do Meteor.yournamespace.MyClass :P
--EDIT
Then you could create a meteor-extend.d.ts file and do something like:
/// <reference path="main.d.ts" />
declare module Meteor {
var yournamespace: any;
}
Now you can remove the <any> before Meteor and Typescript will not complaint.

Where to put native code for push notifications with new Meteor Mobile platform

After reviewing the new Mobile features with latest 1.0 version of Meteor, I'm not seeing where I would modify the Cordova code to add custom capabilities. For instance, I want to implement push notifications for my application on both iOS and Android. In both cases I would need to write some native code so that I could get devices registered and accept push notification messages.
Currently, I'm using MeteorRider to accomplish this and it works great. I have 3 separate projects for Meteor, Android and iOS. In the latter 2, I put the native code there necessary to accomplish this. One thing is for certain, you have to update the bootstrap classes in Cordova to allow registrations to work.
In Meteor 1.0, how would I go about accomplishing this with the out-of-the-box mobile feature?
Here's the objective-C code for accepting push notification registration responses that is required in Cordova's AppDelegate:
- (void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSLog( #"Device token is: %#", deviceToken);
// Convert to string that can be stored in DB
NSString *regId = [[deviceToken description] stringByReplacingOccurrencesOfString:#"<" withString:#""];
regId = [regId stringByReplacingOccurrencesOfString:#">" withString:#""];
regId = [regId stringByReplacingOccurrencesOfString: #" " withString: #""];
[[ApplePushNotificationService sharedInstance] application:application uploadDeviceToken:regId];
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
NSLog(#"Failed to get token, error: %#", error);
}
TL;DR : The cordova project is in the .meteor/local/cordova-build subfolder.
The default AppDelegate.m gets created in the .meteor/local/cordova-build/platforms/ios/***YOUR_APP_NAME***/Classes subfolder.
If you add a top-level folder called cordova-build-override to your meteor project, the directory tree that it contains will be added to the .meteor/local/cordova-build folder just before the build and compilation step.
So, put your custom AppDelegate.m in a new folder called cordova-build-override/platforms/ios/***YOUR_APP_NAME***/Classes .
mkdir -p cordova-build-override/platforms/ios/foo/Classes
cp .meteor/local/cordova-build/platforms/ios/foo/Classes/AppDelegate.m cordova-build-override/platforms/ios/foo/Classes
The Meteor-Cordova integration page on the GitHub Meteor wiki is the best place (so far) to find the details of cordova development with meteor.
You put your cordova-specific code in plain javascript. It's best not to modify the native code if at all possible; instead, see if you can write your own cordova plugin and use it from your meteor app. The cordova PushPlugin plugin might do what you're looking for, but if not, you can use it as a reference.
This example below will create a new iOS app that uses a non-meteor cordova plugin, from scratch.
NOTE: This is a bare minimum example. Look at the meteor cordova camera plugin for a full example. The code below is based on that plugin.
# create a meteor app foo
meteor create foo
cd foo
# add the iOS cordova platform
meteor add-platform ios
# create a new meteor package, foo-camera.
# NOTE: You need to substitute your own meteor.com developer ID here
meteor create --package your_meteor_developer_id:foo-camera
Now, edit the packages/your_meteor_developer_id:foo-camera/package.js file to add the following:
// Add the camera cordova plugin at version 0.3.3
Cordova.depends({
'org.apache.cordova.camera': '0.3.3'
});
EDIT 1: This causes the plugin to be downloaded to your cordova plugins folder.
You can refer to a git tarball instead of a version number e.g. :
Cordova.depends({
'com.phonegap.plugins.facebookconnect': 'https://github.com/Wizcorp/phonegap-facebook-plugin/tarball/0e61babb65bc1716b957b6294c7fdef3ce6ace79'
});
source: meteor cordova wiki
While we're at it, limit our code to run only on the client, and export our FooCamera object so it can be used in the rest of our meteor javascript:
Package.onUse(function(api) {
api.versionsFrom('1.0');
api.export('FooCamera');
api.addFiles('your_meteor_developer_id:foo-camera.js','client');
});
Edit 2:
If your cordova plugin needs special configuration, you can define this in your meteor app's
mobile configuration file. It will get copied into
your app's config.xml .
E.g.
// ===== mobile-config.js ======
// Set PhoneGap/Cordova preferences
App.setPreference('SOME_SPECIFIC_PLUGIN_KEY','SOME_SPECIFIC_PLUGIN_VAL');
Your app's config.xml will then eventually result in the following:
<preference name="SOME_SPECIFIC_PLUGIN_KEY" value="SOME_SPECIFIC_PLUGIN_VAL"/>
Next, edit the JavaScript file in your package ( packages/your_meteor_developer_id:foo-camera/your_meteor_developer_id:foo-camera.js ) to expose the cordova functionality in a meteor-like manner. Use the official meteor mobile package examples as a reference.
(the code below is stolen shamelessly from the meteor github repo ) :
FooCamera = {};
FooCamera.getPicture = function (options, callback) {
// if options are not passed
if (! callback) {
callback = options;
options = {};
}
var success = function (data) {
callback(null, "data:image/jpeg;base64," + data);
};
var failure = function (error) {
callback(new Meteor.Error("cordovaError", error));
};
// call the cordova plugin here, and pass the result to our callback.
navigator.camera.getPicture(success, failure,
_.extend(options, {
quality: options.quality || 49,
targetWidth: options.width || 640,
targetHeight: options.height || 480,
destinationType: Camera.DestinationType.DATA_URL
})
);
};
Now, add your new (local) package to your meteor app.
meteor add your_meteor_developer_id:foo-camera
Edit your application's main HTML and JS to use your new meteor package.
In your foo.html , replace the hello template with this:
<template name="hello">
<button>Take a Photo</button>
{{#if photo}}
<div>
<img src={{photo}} />
</div>
{{/if}}
</template>
In your foo.js , replace the button click event handler with this:
Template.hello.helpers({
photo: function () {
return Session.get("photo");
}
});
Template.hello.events({
'click button': function () {
var cameraOptions = {
width: 800,
height: 600
};
FooCamera.getPicture(cameraOptions, function (error, data) {
Session.set("photo", data);
});
}
});
Now, plug your device in, make sure it's on the same network as your computer, and start both the meteor server and the ios app.
meteor run ios-device
# If you want to just use the emulator, use the following instead.
# but of course the camera won't work on the emulator.
#meteor run ios
XCode will open. You may need to set up your certificates and provisioning profiles before running your app (from XCode).
In another terminal, tail the logs:
tail -f .meteor/local/cordova-build/platforms/ios/cordova/console.log
Finally, publish your excellent meteor cordova plugin so that everyone else can use it. Edit package.js as per the meteor docs. Then:
cd packages/your_meteor_developer_id\:foo-camera
meteor publish

Meteor/Iron-Router: how to define routes using data from settings.json

For the URL to which a route applies I have a part defined in settings.json, like this
baseUrl: '/private'
My settings are published and accessible through the collections 'Settings' (on the client). So I tried the following:
Meteor.subscribe('settings');
Deps.autorun(function () {
var settings = Settings.findOne():
if (settings) {
Router.map(function () {
this.route('project', {
path: settings.baseUrl + '/:projectId,
controller: 'ProjectController'
});
});
}
});
The problem is that during initialisation the data is not yet on the client available, so I have to wait until the data is present. So far this approach doesn't work (yet). But before spending many hours I was wondering if someone has done this before or can tell me if this is the right approach ?
Updated answer:
I published solution in repository : https://github.com/parhelium/meteor-so-inject-data-to-html
. Test it by opening url : localhost:3000/test
In this case FastRender package is useless as it injects collection data in the end of head tag -> line 63.
Inject-Initial package injects data in the beginning of head tag -> line 106.
Needed packages:
mrt add iron-router
mrt add inject-initial
Source code:
Settings = new Meteor.Collection("settings");
if (Meteor.isClient) {
var settings = Injected.obj('settings');
console.log(settings);
Router.map(function () {
this.route('postShow', {
path: '/'+settings.path,
action: function () {
console.log("dynamic route !");
}
});
});
}
if (Meteor.isServer){
if(Settings.find().count() == 0){
Settings.insert({path:"test",data:"null"});
}
Inject.obj('settings', Settings.findOne());
}
Read about security in the bottom of the page : https://github.com/gadicc/meteor-inject-initial/
OLD ANSWER :
Below solution won't work in this specific case as FastRender injects data in the end of head tag. Because of that Routes are being initialized before injected data is present.
It will work when data from Settings collection will be sent together with html.
You can do that using package FastRender.
Create file server/router.js :
FastRender.onAllRoutes(function(path) {
// don't subscribe if client is downloading resources
if(/(css|js|html|map)/.test(path)) {
return;
}
this.subscribe('settings');
});
Create also publish function:
Meteor.publish('settings', function () {
return Settings.find({});
});
The above code means that if user open any url of your app then client will subscribe to "settings" publication and data will be injected on the server into html and available for client immediately.
I use this approach to be able to connect many different domains to meteor app and accordingly sent proper data.

Meteor Package api.add_files add entire folder

I would like to add an entire folder of files to my package. Instead of adding each file individually, is it possible to add an entire folder of files using api.add_files in the package.js file? Perhaps something like:
Package.on_use(function(api) {
api.add_files(["files/*","client");
});
I don't think there's something like that currently in the public API.
However, you can use plain old Node.JS to achieve what you want to do.
Our package structure looks like this :
/packages/my-package
|-> client
| |-> nested
| | |-> file3.js
| |-> file1.js
| |-> file2.js
|-> my-package.js
|-> package.js
We build a helper function as follow :
function getFilesFromFolder(packageName,folder){
// local imports
var _=Npm.require("underscore");
var fs=Npm.require("fs");
var path=Npm.require("path");
// helper function, walks recursively inside nested folders and return absolute filenames
function walk(folder){
var filenames=[];
// get relative filenames from folder
var folderContent=fs.readdirSync(folder);
// iterate over the folder content to handle nested folders
_.each(folderContent,function(filename){
// build absolute filename
var absoluteFilename=folder+path.sep+filename;
// get file stats
var stat=fs.statSync(absoluteFilename);
if(stat.isDirectory()){
// directory case => add filenames fetched from recursive call
filenames=filenames.concat(walk(absoluteFilename));
}
else{
// file case => simply add it
filenames.push(absoluteFilename);
}
});
return filenames;
}
// save current working directory (something like "/home/user/projects/my-project")
var cwd=process.cwd();
// chdir to our package directory
process.chdir("packages"+path.sep+packageName);
// launch initial walk
var result=walk(folder);
// restore previous cwd
process.chdir(cwd);
return result;
}
And you can use it like this :
Package.on_use(function(api){
var clientFiles=getFilesFromFolder("my-package","client");
// should print ["client/file1.js","client/file2.js","client/nested/file3.js"]
console.log(clientFiles);
api.add_files(clientFiles,"client");
});
We simply use Node.JS fs utils to work with the file system.
