Modern Web Apps training
The Modern Web Apps training aims to empower trainees to:
- Tame modern JS with ES2015+ (even on IE9)
- Internalize what makes a modern webapp and what it can do
- Work with a test-first development cycle
- Write module, decoupled code that is easy to test
- Write their project code so that it keeps complexity in check when scaling in size
- Setup an instant dev feedback loop
- Emphasize mobile-first and offline-first UX patterns and best practices
- Make their webapps installable, edging ever close to native apps experience

Need an in-house / custom training?
For a bespoke training, tailored to your needs, either at your office, in ours or remotely, please describe your context and needs using the following link.
Usually, the core training cost for doing this training in-house, which is a flat fee for up to 10 trainees, is €12,000 net. For international sessions with fewer trainees, we can trim that down: talk to us!Request my in-house / custom training
Intended audience and pre-requisites
The Modern Web Apps training targets first and foremost front-end web developers that have to tackle writing large, feature-rich, optimized webapps that should behave well on a wide range of devices (desktops, smartphones, tablets, kiosks…).**
However, trainees might want to “study up” ahead of time to make learning all of this easier once attending the training proper. Future trainees will likely benefit from browsing this list of quality contents Christophe compiled; an ES2015-specific list is also available.
As for other tech components of the front-end web dev world, a “standard” understanding of the client side is obviously expected: HTML and CSS, that is. No need to be an HTML5 or CSS3 master: even if we will use these, they’re not our core topic and therefore entail no particular requirement.
Finally, it is not necessary to have prior familiarity with unit or integration testing systems, nor with in-code documentation systems. If you have already worked with such tools (JUnit, Test::Unit, RSpec, Cucumber, Capybara, Selenium, etc.) all the better, it’ll only make these subjects easier for you. But we will review all the relevant concepts as we put them to practice.
Unless otherwise specified, predefined-dates, multi-client sessions are held in French, so attendees should be reasonably fluent. You are naturally welcome to book custom dates for your company using the link above.
When the training starts, trainees receive all the related slides and supporting material in a web-based format, so they can easily follow along.
Once the training is done, they also get an extremely content-rich debrief e-mail, a reference archive with all finalized codebases (fully annotated and tested), all related slides and various complementary resources.
- Sessions run 7hr a day, or 4hr12 a half-day, adding up to 14hr, 21hr or 28hr.
- Full days run from 9:30 to 12:30 and 14:00 to 18:00, half-days run from 13:48 to 18:00.
- (For or U.S. friends, that's 9:30a-12:30p / 2p-6p and 1:38p-6p Paris time, respectively.)
- For custom dates booked specifically by your company, the schedule can be adjusted to better suit your needs. In particular, we can use half-days locked on reasonable hours in your timezone, e.g. 9a-12:30p EST or 8a-11:30a PST.
- Every trainee uses their own laptop or workstation.
- Training sessions range from 3 to 10 trainees.
Christophe has been doing professional web work since 1995. He co-created Europe’s first production JSP portal in 1999, moving to J2EE before going with Ruby, Rails and finally Node.js.
A best-selling author of“Bien développer pour le Web 2.0” (“Best practices for modern web development”) at Eyrolles, he also wrote the reference book “Prototype and script.aculo.us” at Pragmatic Programmers, articles in various online magazines (most notably the widely-acclaimed A List Apart), and speaks at a number of conferences big and small.
Christophe is the founder and CTO of Delicious Insights.
With a Masters of Computer Science scored in 2006, Maxime slogged for 5 years through the marshes of Java/Subversion in the FinTech consulting sector…
After a year in Australia in 2009, he turned to much more palatable techs: Ruby, Rails and Git. He started working with Christophe in 2010, joining his R&D engineering team to design and implement an e-commerce solution.
He succeeded Christophe as CTO there in 2012, to join him again 3 years later at DI.
Maxime is an R&D engineer at Delicious Insights.
