--rootBaseUrl [Path:String] if pass it, replace rootDir with rootDirBaseURL in output.
--format ["json" | "markdown"] output format. Default: markdown
Examples
# analyze all ts files in src directory
$ express-router-dependency-graph "src/**/*.ts"
# analyze all ts files in src directory and output json
$ express-router-dependency-graph "src/**/*.ts" --format=json
# analyze all js and ts files in src directory
$ express-router-dependency-graph "src/**/*.ts" "src/**/*.js"
# change rootDir to rootDirBaseURL to output
$ express-router-dependency-graph "src/**/*.ts" --rootBaseUrl="https://github.com/owner/repo/tree/master/src"
# include node_modules
# node_modules, dist, build, test, __tests__ are excluded by default
$ express-router-dependency-graph "src/**/*.ts" --noDefaultExcludes
## Example
Example output: `--format=markdown`
- File: file path
- Method: get | post | put | delete | `use`(express's use)
- Routing: routing path name
- Middlewares: used middlewares
- Note: `app.use("/test", () => { ... })` is shown "Anonymous Function" middleware
- FilePath: source code position
| File | Method | Routing | Middlewares | FilePath |
| ------------ | ------ | --------------- | ------------ |---------------------|
| src/game.ts | | | | |
| | get | /getGameById | requireRead | src/game.ts#L11-L12 |
| | get | /getGameList | requireRead | src/game.ts#L13-L14 |
| | post | /updateGameById | requireWrite | src/game.ts#L15-L16 |
| | delete | /deleteGameById | requireWrite | src/game.ts#L17-L18 |
| src/index.ts | | | | |
| | use | /user | user | src/index.ts#L8-L8 |
| | use | /game | game | src/index.ts#L9-L9 |
| src/user.ts | | | | |
| | get | /getUserById | requireRead | src/user.ts#L10-L11 |
| | get | /getUserList | requireRead | src/user.ts#L12-L13 |
| | post | /updateUserById | requireWrite | src/user.ts#L14-L15 |
| | delete | /deleteUserById | requireWrite | src/user.ts#L16-L17 |`
Example output: `--format=json`
