Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

}

XLIFF Watcher (Optional)

XLIFF Watcher in the build system can detect XLIFF file changes in Firebase in realtime and trigger a new build.

See gulp fetch-xliff and gulp watch-xliff tasks in demo/gulpfile.js

Start Watching:

  gulp watch-xliff --database https://live-localizer-demo.firebaseio.com \
    --service_account ../../live-localizer-demo-service-account.json \
    --on_xliff_change 'npm run fetch-xliff && npm run demo' \
    >../../logfile.txt 2>&1 &
  tail -f ../../logfile.txt

Example XLIFF Watcher processes:

$ gulp watch-xliff --database https://live-localizer-demo.firebaseio.com \
>     --service_account ../../live-localizer-demo-service-account.json \
>     --on_xliff_change 'npm run fetch-xliff && npm run demo' # fetch-xliff options have to be configured

The 'credential' property specified in the first argument to initializeApp() is deprecated and will be removed in the next major version. You should instead use the 'firebase-admin' package. See https://firebase.google.com/docs/admin/setup for details on how to get started.

Notes on XLIFF Watcher:

  • Service account credentials' JSON is required for gulp watch-xliff task
  • --token=notoken option to use the same service account credentials for gulp fetch-xliff task as gulp watch-xliff task
    • demo/getUsers.js script, which uses firebase-admin SDK, is required to use the credentials
  • Otherwise, firebase login:ci token from firebase-tools is required for gulp fetch-xliff task

Local XLIFF Watcher (Optional)

Local XLIFF file changes can be watched real-time via local HTTP server at http://localhost:8887/UPLOADED_XLIFF_FILE

Check "Watch and Load XLIFF" in the local file storage control panel to start watching the local XLIFF file

The following table shows triggered operations whenever the translator saves (overwrites) the local XLIFF file

| Components | Operations | |:-----------|:-----------| | XLIFF Editor | Save (overwrite) the uploaded XLIFF file | | http-server | Provide Local XLIFF Watcher with the XLIFF file status | | Local XLIFF Watcher in Live Localizer | Periodically check the XLIFF file status and fetch it on its updates | | xliff-conv in Live Localizer | Merge the XLIFF updates into the JSON data for running UI strings | | Target Application | Show UI with the updated strings | | Browser Storage | Automatically save the XLIFF file if "Automatic Save" is checked | | Firebase Storage | Automatically upload the XLIFF file if "Automatic Save" is checked | | Firebase | Notify XLIFF Watcher of a child_changed event for the XLIFF file updates | | XLIFF Watcher (watch-xliff gulp task) in the build system | Detect the child_changed event and trigger a new build | | Build system | Start a new build process including fetch-xliff gulp task and I18N, and deploy a new build on the development HTTP server | | Development HTTP server | Provide browsers for translators with the new build | | Reload button in Live Localizer | Detect the new build in 60 seconds and show the tooltip "App Updated" |

HTTP Server for Local XLIFF Watcher Setup

npm install -g http-server
  • For HTTP sites, start local HTTP server at http://localhost:8887 with the root folder containing the XLIFF file
http-server FOLDER_TO_CONTAIN_XLIFF -d false -c-1 -r -a localhost -p 8887 --cors=If-Modified-Since
  • For HTTPS sites, start local HTTPS server at https://localhost:8887 with the root folder containing the XLIFF file

Notes on Local XLIFF Watcher:

  • The XLIFF folder should contain only the target XLIFF file(s) for the project for security.
  • The HTTP server is accessible only from the localhost and disallows directory listing.
  • If the XLIFF file name is prefixed with an unpredictable string, it can serve as a kind of "password" to block malicious access from other local HTTP clients.
  • https-local-server script has to be executed in the same folder as its first execution so that it can find the generated certificates in ./demoCA folder.
  • To work around Issue #76, https-local-server script is required even for HTTP web applications.

Build

Bundle dependent components with polymer-build bundler

With lazy loader live-localizer-lazy.js, live-localizer-main.js and its dependencies are lazily loaded. The dependent components except for region flag images can be bundled with polymer-build bundler as follows.
