Walkthrough

The update shifts the method of configuring environment variables in Umi projects. Instead of using separate .env files for different development stages, it now encourages the use of cross-env in start commands or direct definitions in Umi configuration files based on UMI_ENV.

Changes

File Path	Change Summary
docs/.../env-variables.md	Transitioned from .env.development / .env.production to using cross-env and UMI_ENV based configurations.

🐇✨
In the land of code, where the bits align,
A rabbit hopped through, with a change so fine.
No more juggling dots, in files so vast,
Just a simple switch, and it's changed so fast.
Hop, hop, hooray! The code is clear, 🎉
With Umi's new way, we all cheer!

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json

既然文档都放出去了，注意到之前有人提过类似的 issues？不如直接支持一下更好 🤔

import { existsSync, readFileSync } from 'fs';
import { join as PATH_join } from 'path';
import { parse } from '../../compiled/dotenv';
import { expand } from '../../compiled/dotenv-expand';

export function loadEnv(opts: { cwd: string; envFile: string }) {
  const join = (...args: string[]) => PATH_join(opts.cwd, ...args);

  const files = [
    join(opts.envFile),
    join(`${opts.envFile}.local`),
    process.env.NODE_ENV && join(`${opts.envFile}.${process.env.NODE_ENV}`),
    process.env.NODE_ENV && join(`${opts.envFile}.${process.env.NODE_ENV}.local`),
  ].filter(Boolean) as string[];

  for (const file of files) {
    if (!existsSync(file)) continue;
    const parsed: Record<string, string> = parse(readFileSync(file)) || {};
    expand({ parsed, ignoreProcessEnv: true });
    for (const key of Object.keys(parsed)) {
      process.env[key] = parsed[key];
    }
  }
