babel-plugin-optimize-template-literals

Unbrace literal templates in each TemplateLiteral and optimize them.

`aa${'bb'}cc${foo()}` -> `aabb${foo()}`
`aa${'bb' + 'cc'}dd${1+2+'3'}ee${1+'2'+3}` -> `aabbccdd33ee123`

Install

npm i -D babel-plugin-optimize-template-literals

Options

merging

type: boolean
default: false
Merge adjacent TemplateLiterals and StringLiterals

const a = `aaa${'bbb'}` + `ccc${foo()}` + 'ddd'
=>
const a = `aaabbbccc${foo()}ddd`

Use case

It is useful to optimize template-literals statements after using tsc(TypeScript) with const enum.

export const enum TableName {
    USER = 'users'
}
export const CREATE_TABLE_SQL = `
CREATE TABLE IF NOT EXISTS ${TableName.USER} (name TEXT);
`

After tsc

export const CREATE_TABLE_SQL = `
CREATE TABLE IF NOT EXISTS ${'users'} (name TEXT);

After babel with this plugin

export const CREATE_TABLE_SQL = `
CREATE TABLE IF NOT EXISTS users (name TEXT);
