本文介绍了微信小程序的基本概念和发展历程。微信小程序是一种无需下载安装即可使用的应用，适用于多种场景，包括物联网项目。经过两年的发展，微信小程序已经覆盖200多个细分行业，日活用户达到两个亿。微信小程序的发展带来了更多的就业机会，已经成为中国IT行业的重要创新成果。
1、微信小程序

小程序的一种，英文名Wechat Mini Program，是一种不需要下载安装即可使用的应用，它实现了应用“触手可及”的梦想，用户扫一扫或搜一下即可打开应用。全面开放申请后，主体类型为企业、政府、媒体、其他组织或个人的开发者，均可申请注册小程序。微信小程序、微信订阅号、微信服务号、微信企业号是并行的体系。




微信小程序是一种不用下载就能使用的应用，也是一项创新，经过将近两年的发展，已经构造了新的微信小程序开发环境和开发者生态。微信小程序也是这么多年来中国IT行业里一个真正能够影响到普通程序员的创新成果，已经有超过150万的开发者加入到了微信小程序的开发，与我们一起共同发力推动微信小程序的发展，微信小程序应用数量超过了一百万，覆盖200多个细分的行业，日活用户达到两个亿，微信小程序还在许多城市实现了支持地铁、公交服务。微信小程序发展带来更多的就业机会，2017年小程序带动就业104万人，社会效应不断提升。




2017年1月9日，张小龙在2017微信公开课Pro上发布的微信小程序正式上线。2018年2月，微信官方发布公告称：已对涉及假货高仿、SQ低俗和违规“现金贷”等超过2000个微信小程序，进行永久封禁处理。2019年8月9日，微信向开发者发布新能力公测与更新公告，微信PC版新版本中，支持打开聊天中分享的微信小程序。
