Emsi is a labor market analytics firm that continuously searches millions of job postings across the web. This is the tenth installment of a trending tech series in which I share tech skills that are trending in Emsi’s job postings data. In case you missed it, here is last week’s post on the open-source IT automation software Ansible. Today, we’ll talk about Graphql.
12-month growth rate in unique postings for Graphql: 289%
What is Graphql? Graphql is an open-source query language that is used to load data from a server to a client in whatever shape the client requires. Graphql was initially developed at Facebook and released in 2015. It has been rapidly adopted because it addresses the inherent clumsiness of dealing with REST APIs, where bandwidth and latency are important considerations.
REST APIs have fixed data structures. With increasingly complex applications, that generally means multiple queries are needed, over-fetching data (i.e. returning more data than was needed), and wasting bandwidth. Graphql allows applications to use a single query to return the exact data needed, saving bandwidth and reducing latency.

The table below shows the in-demand skills around Graphql from job postings side-by-side with the actual skills of people currently employed with the skill Graphql on their profile. This data is available in Analyst, where we’ve combined our job posting data with detailed employment data from over 106 million professional profiles.
