本指南解释了如何使用 bitbucket pipelines 将 eslint 结果集成到 bitbucket pull 请求中。您将学习如何生成 json 格式的 eslint 报告,使用 bitbucket 报告和注释 api 将这些报告作为内联注释发布,以及配置 bitbucket 管道以自动运行 eslint。

生成 json 格式的 eslint 报告

首先,您需要运行 eslint 并以 json 格式输出结果。该文件稍后将用于创建报告和注释。

将 -f 和 -o 参数添加到 eslint 命令中。例如:

eslint . --ext .ts -f json -o eslint-report.json

将 eslint 报告和注释发布到 bitbucket

要直接在拉取请求中显示 eslint 结果,您将使用 bitbucket 的报告 api 和注释 api。

  1. 阅读 eslint json 报告。
  2. 生成包含错误和警告总数的报告。
  3. 基于 eslint 消息发布内联注释。

配置 bitbucket 管道

要将此过程自动化为 ci/cd 工作流程的一部分,您可以设置 bitbucket 管道来运行 eslint、生成 json 报告并发布结果。下面是一个示例 bitbucket-pipelines.yml 文件,可帮助您入门:

image: node:18.13.0pipelines:  default:    - step:        name: ESLint        caches:          - node        script:          - npm install          - npx eslint . --ext .ts -f json -o eslint-report.json  # Run ESLint and save the report        after-script:          - node post-eslint-results.js  # Post results to Bitbucket        artifacts:          - eslint-report.json

笔记

报告在后脚本中发布到 bitbucket,因为如果 eslint 返回非 0 退出代码(如果 eslint 有错误),后续脚本将不会被调用。
