@nilhave 一站式信息系统开发平台： https://enhancer.io

如果是做信息系统，就用 enhancer 吧

从输入的角度来讲：
攻击者可以绕过前端直接伪造 http 请求输入包含富文本的内容，所以防范一定是在服务器端做的，只不过后端同学有可能不知道怎样的 html 是合法安全，怎样不安全，需要前端配合告知白名单。
从输出的角度来讲：
前端拿到字符串去页面渲染的时候应该根据业务需要决定哪些标记不能出现，哪些可以，现在的模板渲染都自带了 富文本转义，防止 XSS 攻击。enhancer.io

嗯，增删改查用这个减轻工作量：enhancer.io ，专心搞大数据

看看是否能帮助你减轻工作量： https://enhancer.io

题主抵触的是毫无目的更换技术栈带来的让自己额外花精力学习的成本，而非 nodejs 技术本身吧

企业级开发用 nodejs 开发的话可以不用写代码： https://enhancer.io

如果是做企业级应用开发的话，后端不会写 SQL 几乎无法干活。互联网应用情况可能稍微好一点。比如很普通的财务总账 SQL：

SELECT AB.subject_code code, AB.subject_name name
, IFNULL(AB.debit_amount_init, 0) debit_amount_init
, IFNULL(AB.credit_amount_init, 0) credit_amount_init
, IFNULL(AB.debit_amount_curr, 0) debit_amount_curr
, IFNULL(AB.credit_amount_curr, 0) credit_amount_curr
, IFNULL(C.debit_amount_end, 0) debit_amount_end
, IFNULL(C.credit_amount_end, 0) credit_amount_end
, IFNULL(D.debit_amount_total, 0) debit_amount_total
, IFNULL(D.credit_amount_total, 0) credit_amount_total
FROM
(SELECT B.subject_code, B.subject_name
, A.debit_amount_init, A.credit_amount_init
, B.debit_amount_curr, B.credit_amount_curr
FROM
(SELECT subject_code
, subject_name
, SUM(debit_amount) debit_amount_init
, SUM(credit_amount) credit_amount_init
FROM accounting_document_item adi, accounting_document ad
WHERE adi.doc_id = ad.id
AND date_format(accounting_date, '%Y%m') < CONCAT(@12-YEAR@, @12-MONTH@)
GROUP BY subject_code, subject_name) A
RIGHT JOIN
(SELECT subject_code
, subject_name
, SUM(debit_amount) debit_amount_curr
, SUM(credit_amount) credit_amount_curr
FROM accounting_document_item adi, accounting_document ad
WHERE adi.doc_id = ad.id
AND date_format(accounting_date, '%Y%m') = CONCAT(@12-YEAR@, @12-MONTH@)
GROUP BY subject_code, subject_name) B
ON A.subject_code = B.subject_code) AB
LEFT JOIN
(SELECT subject_code

, SUM(debit_amount) debit_amount_end
, SUM(credit_amount) credit_amount_end
FROM accounting_document_item adi, accounting_document ad
WHERE adi.doc_id = ad.id
AND date_format(accounting_date, '%Y%m') <= CONCAT(@12-YEAR@, @12-MONTH@)
GROUP BY subject_code, subject_name) C
ON AB.subject_code = C.subject_code
LEFT JOIN
(SELECT subject_code

FROM accounting_document_item adi, accounting_document ad
WHERE adi.doc_id = ad.id

GROUP BY subject_code, subject_name) D

看看这个是否能用得上：enhancer.io
