1.6.0 Ignores my module config template.dir

[jedsmith13]

Config:

template: {
  dir: __dirname + '/templates',
  adapter: new HandlebarsAdapter(),
  options: {
    strict: true,
  },
},

Service:

  template: 'order-forward',

This worked with 1.5.1 but on upgrading to 1.6.0 it stopped working. However, if I changed the template to,

  template: __dirname + '/../templates/order-forward',

it works again.

The error thrown is:

Same issue here

Same issue here, with ejsadapter too.
Tried with node 14 and node 15.

Looking at lib/adapters/handlebars.adapter.ts I've figured it out: the mail template must start wit './'! I'm using 1.6.0.

  createMailerModuleOptions(): MailerOptions {
    const options =
     {
      transport: {
        host: process.env.MAIL_HOST,
        port: process.env.MAIL_PORT,
        secure: false, // TODO - Upgrade later with STARTTLS
        ignoreTLS: true,
      },
      defaults: {
        from: process.env.MAIL_FROM_ADDRESS,
      },
      template: {
        dir: `${process.cwd()}/src/shared/provider/email/template/`,
        adapter: new HandlebarsAdapter(),
        options: {
          strict: true,
        },
      },
    };

    return options;
  }

  public test(): void {
    this
      .mailerService
      .sendMail({
        to: 'me@myself.com',
        subject: 'Testing Nest Mailermodule with template ✔',
        template: `./index.hbs`,
        context: {
          code: 'cf1a3f828287',
          username: 'john doe',
        },
      })
      .then((success) => {
        console.log(success)
      })
      .catch((err) => {
        console.log(err)
      });
  }
}

That's really obscure. The existence of a global template option made think that the email template option should be only 'index', not './index'.

That was it! Thanks a lot!

That's a breaking change with v1.6.0
With version 1.5.1 its fine using templates like bellow

this.mailerService.sendMail({
      ...
      template: 'password-reset',
      ...
});

with version 1.6.0 it has to be changed to

this.mailerService.sendMail({
      ...
      template: './password-reset',
      ...
});

as @lzkill mentioned already

[knownasilya]

Yeah, this is not intuitive at all, and if you read the code it makes you think the template is in the same directory as the usage.

[victororlyk]

for me trick with ./ didn't worked, I have switched to 1.5.1 and

     template: {
        dir: join(__dirname, 'templates'),
        adapter: new HandlebarsAdapter(), // or EJS adapter
        options: { strict: true },
      },

worked for me

My directory

The project needs to be packaged at the end, so package the template static file in the dist directory. Remember to add the configuration in the nest-cli.json

{
  "collection": "@nestjs/schematics",
  "sourceRoot": "src",
  // Add this configuration
  "compilerOptions": {
    "assets": ["templates/**/*"]
  }
}

  this.mailerService.sendMail({
      to: 'xxxxx@x.com',
      from: 'yyyyy@yy.com',
      subject: 'test',
      // I wrote it like this before  template: 'welcome.pug', but I failed
      // Then I changed it to look like this
      template: './welcome.pug'
    })
    .then((res) => { console.log(res) })
    .catch((e) => { console.log(e) });



 useFactory: () => ({
    transport: 'smtps://xxx@xx.com:pass@smtp.xx.com',
    defaults: {
      from: '"nest-modules" <modules@nestjs.com>'
    },
    template: {
      dir: path.join(__dirname, 'templates'),
      adapter: new PugAdapter(),
      options: {
        strict: true
      }
    }
 })
