是否可以在本地测试Firebase触发器? [英] Is it possible to test a Firebase trigger locally?

问题描述

将firebase-functions与Node和exports.foo = functions.database.ref('/object').onWrite(event => {});一起使用.

Using firebase-functions with Node and exports.foo = functions.database.ref('/object').onWrite(event => {});.

我可以部署到云中并进行很好的测试...，并且可以使用firebase serve --only functions在本地轻松地测试http类型的功能.

I can deploy to the cloud and test just fine ... and I can easily test http-type functions locally using firebase serve --only functions.

但是，我没有一种在本地测试触发的方法.是否有可能?怎么样?

However, I don't see a way to test triggers locally. Is it possible? How?

推荐答案

现在可以做到这一点.我终于找到这篇清楚的中等文章，解释了它的用法:

This in now possible. I finally find this clear medium post which explain how do it : https://medium.com/@moki298/test-your-firebase-cloud-functions-locally-using-cloud-functions-shell-32c821f8a5ce

要在本地运行触发器，请使用功能外壳"工具:

To run a trigger locally, use the "functions shell" tool :

1-我的Firestore代码(中级使用RealTime数据库):

1 - My code for firestore (the medium post use RealTime Database) :

exports.testTrigger = functions.firestore
.document('messages/{messageId}')
.onCreate((snapshot, context) => {
    let message = snapshot.data()
    return snapshot.ref.set({
        ...message,
        status : 'sent' 
    })
})

2-我在终端中运行firebase shell函数

2 - I run the firebase shell functions in the terminal

firebase functions:shell

3-我用参数中的数据调用"testTrigger"云函数触发器

3 - I call my "testTrigger" cloud function trigger with data in parameter

testTrigger({text:"hello"})

4-我的Firestore数据库中有一个由我的触发器更新的新消息"

4- My firestore database has a new "message" updated by my trigger
