About
The International JavaScript Conference (iJS) Berlin belongs to the same global full-stack JavaScript series as the London, Munich and San Diego editions, and is held alongside a technology expo in the German capital. The 2027 edition runs from 14 to 18 June 2027 at the Maritim proArte Hotel on Friedrichstraße, with workshop and bootcamp days framing the main conference and an expo on 15 and 16 June; remote tickets provide a livestream with interactive Q&A. The programme spans the modern JavaScript and TypeScript ecosystem — React, Angular, Vue and emerging frameworks, Node.js backends, web performance, security, testing and progressive web apps — with a growing emphasis on AI-assisted development workflows. The audience is professional web developers, software architects and team leads building production applications. Attendees gain full-day workshops led by international experts, a cross-framework view of where the ecosystem is moving, and networking with the Berlin tech community. For full-stack and front-end developers in Europe, iJS Berlin is a substantial mid-year deep dive into the JavaScript platform.

Planning your trip to Berlin
Contains sponsored linksiJS Berlin runs 14–18 June 2027 at the Maritim proArte Hotel on Friedrichstraße, in the middle of Mitte — the five-day format with workshop days bookending the core conference means most attendees get at least one free Berlin evening per day of content. Mid-June is the city's sweet spot: 22–25°C, beer gardens and Spree-side bars at full tilt, and daylight past 9:30 p.m. The venue's location puts Museum Island and the government quarter within a 15-minute walk.
Getting there & around
Berlin Brandenburg Airport (BER) connects to the city by the FEX airport express and S-Bahn; Friedrichstraße station, two blocks from the venue, is reachable in 35–45 minutes with one change at Hauptbahnhof or a direct regional train. Berlin's U-Bahn, S-Bahn and trams run on a single ticket — a multi-day AB-zone pass covers everything a conference visitor needs, including the airport leg.
Skip the taxi queue — pre-book a fixed-price airport transfer with Welcome Pickups. Exploring beyond the city? compare rental cars on EconomyBookings.
Staying connected
German 5G is reliable across central Berlin, and EU visitors roam at no extra cost. Attendees from outside the EU should set up an eSIM before departure — conference Wi-Fi is no substitute for data on the U-Bahn. Set up an eSIM with Airalo before you board and you're online the moment you land.
After the sessions
Museum Island. Five world-class museums share a UNESCO-listed island ten minutes' walk from the conference hotel. If time is short, pick the Neues Museum for Nefertiti or the Pergamonpanorama; late-afternoon slots are quietest. A single island ticket covers multiple houses — realistic to use on a workshop-free afternoon. Tickets on Tiqets →
Reichstag dome at sunset. The glass dome above the German parliament gives a 360° view over the Tiergarten and the government quarter, and June bookings at 8–9 p.m. coincide with golden hour. Entry is free but requires online registration with passport details a few days ahead — organize it before you fly. Twenty minutes on foot from Friedrichstraße.
Spree evening boat tour. One-hour cruises loop from piers near Friedrichstraße through the government district and Museum Island — in June the 7 p.m. departures run in full daylight and catch the parliament buildings glowing. It is the lowest-effort sightseeing available to a conference visitor: board two blocks from the venue, disembark in time for dinner. Tickets on Tiqets →
Prenzlauer Berg beer gardens. Two U-Bahn stops north, the Kastanienallee and Kollwitzplatz area offers the city's most relaxed summer evenings — Prater Garten, Berlin's oldest beer garden, anchors the neighborhood. June nights stay warm enough to sit out until closing. A natural setting for the hallway-track conversations the conference day didn't finish.
Good to know
How do I get from BER Airport to the iJS venue on Friedrichstraße?
Take the FEX or a regional train toward Hauptbahnhof and change to the S-Bahn for Friedrichstraße, or catch a direct RE train when timed right; the journey takes 35–45 minutes. The Maritim proArte is a five-minute walk from Friedrichstraße station.
What is Berlin weather like in mid-June?
Warm and mostly sunny: highs around 22–25°C with occasional thunderstorms, and daylight until about 9:30 p.m. Evenings cool to a comfortable 15°C — bring one light layer.
Do restaurants in Berlin take cards?
Most do, but Berlin remains more cash-fond than other capitals; smaller cafés, kiosks and some beer gardens are cash-only. Keep €50 or so in notes to avoid surprises.
